Poem

🐇 I hopped through configs, logs, and tests,
With docker burrows, all the bests.
Traces shimmer, queues hum low,
Songs and storages start to grow.
This rabbit cheers your service fleet—
A tidy hop from code to beat.

peaceiris/actions-gh-pages v3 v4 compatibility runner incompatible

💡 Result:

The peaceiris/actions-gh-pages action v3 and v4 releases are distinct major versions with different underlying Node.js runtime requirements [1][2][3]. Key compatibility details: - Version 3: Originally designed for older Node.js runtimes (e.g., Node.js 16) [1][3]. GitHub Actions runners have progressively deprecated older Node versions, leading to warnings or incompatibility errors when using legacy versions of actions [4][5]. - Version 4: Upgraded to use a newer Node.js runtime (initially Node.js 20, and updated to Node.js 24 in recent commits to maintain compatibility with modern GitHub runners) [1][6][5]. If you are encountering warnings or runner compatibility issues, you should migrate to version 4 [7][8]. The v4 release is the current recommended major version for GitHub Actions compatibility [7]. To resolve "incompatible" runner warnings, update your workflow configuration to point to v4: - uses: peaceiris/actions-gh-pages@v4 Note that GitHub Actions runners began defaulting to Node.js 24 in June 2026 [5]. To ensure full compatibility with these environment changes, ensure you are using the latest version of the action [5].

GitHub Actions Node.js 12 16 20 runner support peaceiris-gh-pages

💡 Result:

As of June 18, 2026, GitHub Actions has officially transitioned to Node.js 24 as the default runtime environment for runners [1][2]. This change took effect on June 16, 2026 [1][2]. Support Summary: Node.js 12 and Node.js 16: These versions are fully deprecated and no longer supported on GitHub Actions runners [3][4]. GitHub migrated actions from Node 12 to 16 in 2023 [3] and subsequently from 16 to 20 [4]. Node.js 20: This version reached its end-of-life in April 2026 [1][5]. While it served as the primary runtime following the Node 16 deprecation, it has now been replaced by Node.js 24 [1][2]. Users who still need to run actions on Node.js 20 temporarily may use the environment variable ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true, though this is a short-term fallback [1][6]. peaceiris/actions-gh-pages: The project has been updated to support Node.js 24 [7]. Users should ensure they are using the latest version of the action to align with the current runner requirements [8][7]. You can verify the latest release and runtime specifications in the official repository [9][7]. General Guidance: For all GitHub Actions, it is strongly recommended to update workflows to use the latest versions of actions that support Node.js 24 [1]. The deprecation of older Node.js runtimes is part of a phased rollout; if your workflows rely on deprecated versions, you may see warning annotations at the end of your jobs [1][5].

Upgrade peaceiris/actions-gh-pages to v4; v3 is incompatible with current Node.js 24 runners.

Line 44 uses peaceiris/actions-gh-pages@v3, which relies on Node.js 16 and is incompatible with GitHub Actions runners now defaulting to Node.js 24 (as of June 2026). This will cause deployment failures. Upgrade to v4, which supports Node.js 24.

Remove the undefined matrix guard from the test step.

Line 64 references matrix.os, but no matrix is defined for this job. This prevents the test step from executing entirely—the undefined variable causes the condition to fail. Since the job statically runs on ubuntu-latest, the conditional check is unnecessary.

Build artifact selection fails with assemble and container runs as root.

Using assemble produces multiple jars in Spring Boot projects (plain jar, executable jar, and variants), so the wildcard *.jar copy will fail. Additionally, the runtime container has no USER directive and executes as root.

In `@config-service/Dockerfile` around lines 13 - 19, The Dockerfile has two
issues: the gradlew command uses assemble which generates multiple JAR files,
causing the wildcard COPY *.jar pattern to fail, and the runtime container has
no USER directive so it executes as root. Replace the assemble task with bootJar
in the RUN command to generate a single executable JAR, update the COPY command
to target the specific built jar (such as using a more specific pattern like
*-SNAPSHOT.jar or the exact jar name if known), and add a USER directive before
the WORKDIR instruction to run the container as a non-root user.

The gradlew.bat file uses Unix line endings (LF-only) instead of the Windows standard (CRLF). Batch script parsers expect CRLF; LF-only can cause GOTO/CALL label parsing failures and 512-byte boundary issues, making the script non-functional on Windows.

Additionally, static analysis flags three other issues in the script:

  1. Line 29: Unsafe SET command without quotes. If the path contains spaces, it will fail.
  2. Line 87: Complex quote escaping may not be handled correctly by the batch parser.
  3. Line 45: JAVA_EXE used in command without validation.
🔧 Proposed fix for line endings and SET quoting

Convert the file to Windows (CRLF) line endings and apply these fixes:

-set DIRNAME=%~dp0
+set "DIRNAME=%~dp0"

At line 87, use a safer comparison pattern:

-if %ERRORLEVEL% equ 0 goto mainEnd
+if errorlevel 1 goto fail

Validate JAVA_EXE before use:

-%JAVA_EXE% -version >NUL 2>&1
+if not exist "%JAVA_EXE%" (goto fail)
+"%JAVA_EXE%" -version >NUL 2>&1

After applying these changes, convert the file from LF to CRLF line endings using:

  • Git: git config core.autocrlf true and recommit
  • DOS2Unix: dos2unix gradlew.bat
  • Or manually in your editor: open with Notepad++, set line ending to Windows (CRLF), save

Spring @ExceptionHandler parameter type mismatch exception handling behavior

💡 Result:

In Spring applications, a parameter type mismatch (e.g., passing a string where an integer is expected) during request binding typically throws a MethodArgumentTypeMismatchException [1][2][3]. This exception is a subclass of TypeMismatchException [1][2]. To handle this behavior using @ExceptionHandler, you can define a method within a @Controller or a global @ControllerAdvice class that explicitly catches these exceptions [4][5]. Implementation Strategy: It is recommended to catch MethodArgumentTypeMismatchException specifically, as it provides access to the problematic parameter name, the required type, and the value that caused the mismatch [1][2][3]. Example: @ControllerAdvice public class GlobalExceptionHandler { @ExceptionHandler(MethodArgumentTypeMismatchException.class) public ResponseEntity handleTypeMismatch(MethodArgumentTypeMismatchException ex) { String name = ex.getName; String type = ex.getRequiredType!= null? ex.getRequiredType.getSimpleName: "unknown"; String message = String.format("Parameter '%s' should be of type '%s'", name, type); return new ResponseEntity<>(message, HttpStatus.BAD_REQUEST); } } Key Considerations: 1. Specificity: While you can catch the parent TypeMismatchException, targeting MethodArgumentTypeMismatchException is preferred for better access to request-specific metadata [1][3]. 2. Scope: Defining the handler in a @ControllerAdvice class allows you to manage these exceptions globally across all controllers [4][5][6]. 3. Method Signatures: @ExceptionHandler methods support flexible signatures, allowing you to inject objects like WebRequest, HttpServletRequest, or the exception instance itself to construct detailed error responses [7][3][8]. 4. Order: If multiple handlers match, Spring uses an ExceptionDepthComparator to prioritize the most specific exception type match [4][9]. Ensure your exception handling methods are specific to avoid ambiguity [4].

🌐 Web query:

Spring @ExceptionHandler method signature exception parameter type matching compatibility

💡 Result:

In Spring, @ExceptionHandler method parameters serve as a key mechanism for matching thrown exceptions to handler methods [1][2]. When an exception is thrown, Spring resolves the appropriate handler method by considering both the exception types declared in the @ExceptionHandler annotation and the exception type declared as a method argument [2][3]. Key aspects of exception parameter matching include: 1. Exception Type Mapping: If the @ExceptionHandler annotation does not explicitly narrow the exception types via its value attribute, Spring uses the exception type declared in the method signature as the primary mapping hint [2][4]. You can declare the parameter as a specific exception type or as a more general superclass (e.g., Exception) [1][4]. 2. Cause Level Resolution: Spring can match against both the top-level exception being propagated and nested causes within wrapper exceptions (e.g., an IOException wrapped inside an IllegalStateException) [1][5]. As of Spring Framework 5.3, the framework can match at any cause level, whereas earlier versions were limited to the immediate cause [1][4]. 3. Resolution Priority (ExceptionDepthComparator): If multiple handler methods match a thrown exception, Spring uses the ExceptionDepthComparator to sort them [1][6]. In this process, a match to a root exception (a more specific match) is generally preferred over a match to a cause exception [1][5]. Within a single controller or @ControllerAdvice class, this depth comparison determines the winner [5]. 4. Best Practices: - It is highly recommended to be as specific as possible in the method argument signature to reduce ambiguity and prevent mismatches between root and cause exceptions [1]. - If you have multiple exception types that require distinct handling, consider splitting them into individual @ExceptionHandler methods, each matching a single specific exception type through its parameter signature [1]. - If an @ExceptionHandler method determines it cannot handle a specific exception instance, it can rethrow the exception. The exception will then continue propagating through the remaining resolution chain as if that handler had not matched [5]. When using a @ControllerAdvice, global exception handlers are applied after local handlers defined within the controller class itself [7]. Therefore, a specific cause match in a higher-priority @ControllerAdvice bean may be preferred over a root match in a lower-priority one [5].

Fix bad-request handler signature mismatch.

Line 25 accepts InvalidRequestException, but Line 24 declares IllegalArgumentException and HttpMediaTypeNotSupportedException too. Those exceptions won't match the method parameter type and will bypass this handler, resulting in unintended 500 responses instead of 400 handling.

- Around line 62-63: The SecurityConfig class currently disables CSRF protection
globally across all security matchers using
csrf(AbstractHttpConfigurer::disable), which is overly broad and creates a
security vulnerability since form login is enabled on the /login endpoint.
Remove the blanket CSRF disable and instead configure CSRF protection
selectively by using a more granular approach that keeps CSRF enabled by default
but disables it only on specific endpoints that truly require it (such as
certain OAuth2 endpoints that cannot support CSRF tokens). This ensures CSRF
protection remains active for sensitive endpoints like /login while allowing
exceptions only where necessary.
- Around line 67-69: The authenticationSuccessHandler method in SecurityConfig
is redirecting with hardcoded OAuth2 parameters, which loses the original
request's security-critical parameters like state (for CSRF protection) and
code_challenge (for PKCE), as well as client-specific settings. Instead of
constructing a new redirect URL with fixed parameters, extract the original
OAuth2 authorization request parameters from the request object (including
state, code_challenge, client_id, redirect_uri, and scope), and reconstruct the
redirect URL by appending these preserved parameters. This ensures the original
authorization flow is resumed with all its security attributes intact.
- Around line 160-163: The jwtDecoder() method in SecurityConfig hardcodes the
JWT HMAC secret as a string literal, which is a security vulnerability. Move the
secret string to externalized configuration by adding an auth.jwt.hmac-secret
property to application.yml and application-docker.yml files. Then inject this
property value into the SecurityConfig class using the Value annotation and
replace the hardcoded secret string in the jwtDecoder() method with the injected
property value. This allows the secret to be managed externally and enables key
rotation without recompilation.
- Around line 45-52: The authorizationServerSecurityFilterChain method only
applies security rules to specific paths and leaves all other routes
unprotected, including the H2 console endpoint and any future endpoints outside
the configured matchers. Create a new SecurityFilterChain bean method with
`@Order`(2) that acts as a fallback handler for all remaining routes not matched
by the first chain (which has `@Order`(1)). This fallback chain should use a
default securityMatcher or no matcher at all to catch all unmatched requests,
and apply appropriate authorization rules (such as requiring authentication for
non-public endpoints) to ensure comprehensive security coverage across the
entire application.

In `@auth-service/src/main/java/com/audio/auth/controller/AuthController.java`:
- Around line 139-143: The redirect_uri parameter in the authUrl construction
within AuthController does not match the redirect URIs configured in the token
exchange and registered client settings. Identify the correct redirect_uri value
that is used in your token exchange endpoint and registered client configuration
(check your OAuth2 server configuration or registration settings), then update
the redirect_uri parameter in the authUrl string to use the same value
consistently across all OAuth2 endpoints. Ensure this redirect_uri matches
exactly in the authorization request, token exchange, and client registration to
avoid redirect URI validation failures.
- Line 24: The hardcoded OAuth client credentials in the setBasicAuth() method
calls throughout the AuthController class are security vulnerabilities. Replace
all occurrences of hardcoded client ID "auth-client" and secret "secret" with
values retrieved from secure configuration sources such as environment variables
or application properties. This applies to all setBasicAuth() calls at the
specified locations (24, 49, 73, 97, 120). Ensure the configuration values are
injected via dependency injection or configuration framework rather than being
embedded in the source code.
- Line 20: The RestTemplate instantiation in AuthController lacks configured
connect and read timeouts, which can cause thread pool exhaustion when upstream
services are slow. Replace the default RestTemplate initialization with a
properly configured instance that uses a ClientHttpRequestFactory (such as
HttpComponentsClientHttpRequestFactory or SimpleClientHttpRequestFactory) with
explicit connect timeout and read timeout settings. Apply this configuration
consistently across all five endpoints: /token, /refresh, /client-credentials,
/introspect, and /revoke, or better yet, create a shared RestTemplate bean to
avoid duplication.

In `@qa-service/Dockerfile`:
- Around line 16-21: The Dockerfile final stage runs as root by default,
creating a security vulnerability if the container is compromised. Add a USER
directive before the CMD instruction that specifies a non-root user. First
create a non-root user in the Dockerfile using Alpine Linux package manager
commands (addgroup and adduser or equivalent), ensure the user has permission to
access the /app directory by adjusting file ownership if necessary, and then add
a USER directive to switch to that non-root user before the CMD instruction that
runs java with app.jar.

In
`@qa-service/src/test/java/com/audio/test/integration/ResourceIntegrationTest.java`:
- Around line 8-10: The ResourceIntegrationTest class is empty and contains no
test methods, which means it will not execute any tests during CI runs. Add at
least one test method to the ResourceIntegrationTest class by creating a method
annotated with `@Test` that performs meaningful integration testing for the
resource functionality. This will ensure the test class is properly activated
and validates the expected behavior during the CI pipeline.

In `@qa-service/src/test/java/com/audio/test/steps/ResourceSteps.java`:
- Around line 19-30: The test steps upload(), verify(), and checkMessage() have
incomplete implementations that create false-positive test results. The upload()
method should perform an actual file upload operation and store the returned
resource ID for later verification. The verify() method currently checks a
hardcoded resource ID of 1, but should instead use the ID returned from the
upload operation to verify the correct resource was created. The checkMessage()
method is empty and should implement logic to verify that the message processor
received the expected message from the uploaded resource. This ensures the
scenario actually validates the complete flow of uploading a file, receiving a
resource ID, and confirming the processor handled it.

In `@song-service/src/test/java/com/audio/song/SongApplicationTests.java`:
- Around line 5-9: The contextLoads method in the SongApplicationTests class is
currently an empty no-op test that doesn't verify anything. Add a meaningful
assertion to verify that the Spring application context has loaded successfully,
such as injecting the ApplicationContext bean and asserting that it is not null,
or using Spring's built-in test utilities to ensure the Spring context
initialization completes without failures.

In `@song-service/src/test/java/com/audio/song/SongServiceSecurityTest.java`:
- Around line 97-100: The adminRoleCanDeleteSong() test method does not stub the
songService.deleteSongs() method call, causing Mockito to return null by
default, which triggers a NullPointerException when the SongController attempts
to call .size() on the null return value. Before the mockMvc.perform() call in
adminRoleCanDeleteSong(), add a mock setup using Mockito.when() to stub the
songService.deleteSongs() method to return a non-null value such as an empty
list or a list containing test song IDs, ensuring the controller receives valid
data to process.

In `@tools/dashboards/gateway-metrics.json`:
- Around line 16-17: The dashboard queries in gateway-metrics.json are filtering
for job="api-gateway", but the Prometheus scrape configuration defines the job
label as job="gateway", causing a label mismatch that renders all panels empty.
Update all 8 query expressions at lines 16, 30, 49, 54, 59, 73, 87, and 106 by
replacing job="api-gateway" with job="gateway" in each expr field to align with
the actual Prometheus configuration and ensure the metrics display correctly on
the dashboard.

In `@ui-service/src/components/Login.js`:
- Around line 29-50: The Login component's input fields rely solely on
placeholders without associated labels, and the error message is not announced
to assistive technologies. Add label elements with htmlFor attributes that
properly associate with each input field (the username input with type="text"
and the password input with type="password"), using unique id attributes on the
inputs. Additionally, update the error message paragraph element that renders
when error exists to include aria-live="polite" and aria-role="alert" to ensure
screen readers announce the error message to users immediately when it appears.

In `@ui-service/src/components/StoragesTable.js`:
- Around line 18-27: In the fetchStorages function, the .then() success block
sets storages and loading state but does not clear the error state, leaving
stale error messages visible even after successful retry. Add a call to clear
the error state (setError to null or empty string) in the .then() block when the
fetch succeeds. Apply the same fix to the other storage operation functions
mentioned in the comment (around lines 30-38 and 41-47, which likely handle add
and delete operations) by ensuring their .then() blocks also clear any previous
error state when operations succeed.
- Line 43: The DELETE request in the axiosInstance.delete call is using a path
variable for the storage ID, but the backend StorageController endpoint expects
it as a query parameter. Update the axiosInstance.delete call to use a query
parameter syntax instead of a path variable, changing from /storages/${id} to
/storages?id=${id} to match the backend's `@RequestParam` expectation.

In `@ui-service/src/services/authService.js`:
- Around line 7-12: The authService.js login flow is using an incorrect OAuth2
configuration that doesn't match the auth-server setup. The client_id is
hardcoded as 'gateway' which is not registered in the auth-server, and the
grant_type is set to 'password' which is not supported by any client on the
auth-server. Update the OAuth2 configuration in the fetch request to use one of
the registered clients ('auth-client' or 'storage-client') as the client_id, and
change the grant_type from 'password' to one of the supported grant types
('authorization_code', 'refresh_token', or 'client_credentials') that matches
the UI login flow requirements and is configured for the chosen client.

Nitpick comments:
In `@auth-service/src/main/resources/logback-spring.xml`:
- Around line 35-38: The root logger configuration block is commented out in the
logback-spring.xml file, which prevents log events from being routed to the
declared CONSOLE and LOGSTASH appenders. Uncomment the root logger element (the
block with level="INFO" that contains the appender-ref tags for CONSOLE and
LOGSTASH) to activate the logger binding and ensure that log events are properly
sent to both appenders for observability.

In `@review/review.md`:
- Around line 1-1000: The review document contains Markdown formatting
violations that prevent proper rendering and passing linting checks. Fix these
issues by: (1) adding missing link reference definitions at the end of the
document for citation references [2], [3], [4] used around lines 827 and 894, or
converting them to inline markdown links with format [text](url); (2) removing
extra whitespace around emphasis markers throughout the document where text is
quoted with spaces like " issue " or " Heavy lift " and replacing them with
proper emphasis without surrounding spaces; (3) ensuring all atx-style headings
have exactly one space between the # character(s) and the heading text (e.g., "#
Heading" not "`#Heading`" or "##  Heading"). Search through the entire document
for these patterns and correct them systematically.

In `@song-service/src/test/java/com/audio/song/SongServiceSecurityTest.java`:
- Around line 55-57: The security tests are bypassing the
JwtGrantedAuthoritiesConverter by directly injecting authorities via
jwt().authorities(...) instead of using the actual JWT claim mapping. Replace
the direct authority injection pattern across all affected test methods (the
ones using jwt().authorities(...)) with the claim-based approach using .jwt(jwt
-> jwt.claim("roles", List.of("USER"))) to ensure the actual claim-to-authority
mapping logic is properly tested and any regressions in the SecurityConfig
converter would be caught.

In `@tools/api-tests/module8-security-tests.json`:
- Around line 21-26: The OAuth credentials and test user passwords are hardcoded
directly in the module8-security-tests.json collection file. Replace the
hardcoded values for client_secret (at lines 25 and 50), username, and password
with Postman environment variable references using the syntax {{variable_name}}.
Create corresponding environment variables in a separate Postman environment
file and ensure those variables are left blank in the repository to prevent
accidental secret propagation. Update all four credential fields in the test
collection to use environment variables instead of their current static values.
- Around line 34-35: The response field in the Postman test requests (at lines
34-35 and also at 59-60, 79-80, 99-100, 115-116, 140-141, 156-157, 188-189)
contains empty test scripts, so HTTP status codes are not being validated. For
each request, add Postman test scripts within the response/test section that
assert the expected HTTP status code (200, 201, 204, 401, or 403 depending on
what the security test case should validate). This will ensure that the
automated security tests actually verify the contract behavior rather than just
running without assertions.

In `@ui-service/build.gradle`:
- Around line 42-44: The bootRun task name is misleading because it implies
Spring Boot semantics when it actually starts the React development server via
npm. Rename the task registered as 'bootRun' to a more descriptive name such as
'startUiDevServer' that clearly indicates it starts the React development
server, not Spring Boot. This will prevent confusion in CI pipelines and future
task-name collisions.

In `@ui-service/src/App.js`:
- Around line 11-21: The code contains two separate conditional blocks that both
return the same Login component with identical onLoginSuccess callbacks when the
user is not authenticated. The first block checks for path === '/login' &&
!authenticated while the second checks only !authenticated, making the first
condition redundant. Remove the first if block (checking path === '/login' &&
!authenticated) and keep only the second if (!authenticated) block that handles
all unauthenticated cases, reducing code duplication and drift risk.

In `@ui-service/src/components/ProtectedRoute.js`:
- Around line 4-7: The ProtectedRoute component is triggering a side effect by
setting window.location.href directly in render logic (when isAuthenticated()
returns false). Move this redirect logic out of the render phase by wrapping the
window.location.href assignment in a useEffect hook with appropriate
dependencies. This ensures the redirect happens after the component renders
rather than during render, preventing unpredictable behavior and adhering to
React's principle of pure render functions.

Add a fallback SecurityFilterChain for non-matched routes.

The current SecurityFilterChain with @Order(1) only applies to /oauth2/**, /auth/**, /login, and /error. The H2 console endpoint (/h2-console) enabled in the dev profile is not covered by these matchers and remains unprotected. Additionally, any future endpoints added outside these matchers will be unprotected without an explicit fallback chain.

Suggested fix
 `@Bean`
 `@Order`(1)
 public SecurityFilterChain authorizationServerSecurityFilterChain(HttpSecurity http) {
   ...
 }

+@Bean
+@Order(2)
+public SecurityFilterChain defaultSecurityFilterChain(HttpSecurity http) throws Exception {

Disable CSRF selectively instead of for the entire security matcher scope.

With form login enabled on the /login endpoint (line 53), CSRF protection should remain active. Currently, CSRF is disabled for all paths in the security matcher (/oauth2/**, /auth/**, /login, /error), which permits cross-site POSTs against all of them. Keep CSRF enabled and disable it only on endpoints that require it (e.g., specific OAuth2 endpoints that cannot support CSRF tokens).

In `@auth-service/src/main/java/com/audio/auth/config/SecurityConfig.java` around
lines 62 - 63, The SecurityConfig class currently disables CSRF protection
globally across all security matchers using
csrf(AbstractHttpConfigurer::disable), which is overly broad and creates a
security vulnerability since form login is enabled on the /login endpoint.
Remove the blanket CSRF disable and instead configure CSRF protection
selectively by using a more granular approach that keeps CSRF enabled by default
but disables it only on specific endpoints that truly require it (such as
certain OAuth2 endpoints that cannot support CSRF tokens). This ensures CSRF
protection remains active for sensitive endpoints like /login while allowing
exceptions only where necessary.

Hardcoded authorization redirect ignores original OAuth2 request parameters.

After form login, the success handler should resume the original authorization request (which includes state for CSRF protection and code_challenge for PKCE), not initiate a new one with hardcoded parameters. The current redirect overwrites client-specific parameters (client_id, redirect_uri, scope, state, code_challenge), breaking the OAuth2 flow and weakening CSRF defenses. Extract and reuse the original request parameters instead.

lines 67 - 69, The authenticationSuccessHandler method in SecurityConfig is
redirecting with hardcoded OAuth2 parameters, which loses the original request's
security-critical parameters like state (for CSRF protection) and code_challenge
(for PKCE), as well as client-specific settings. Instead of constructing a new
redirect URL with fixed parameters, extract the original OAuth2 authorization
request parameters from the request object (including state, code_challenge,
client_id, redirect_uri, and scope), and reconstruct the redirect URL by
appending these preserved parameters. This ensures the original authorization
flow is resumed with all its security attributes intact.

Move the JWT HMAC secret from source code to externalized configuration.

Hardcoding the signing/verification secret enables token forgery if source code is leaked and prevents key rotation without recompilation.

UI login flow will fail: "gateway" client and "password" grant type are not configured in auth-server.

The authService.js login attempts to use client_id=gateway with grant_type=password, but the auth-server only registers two clients: "auth-client" and "storage-client". Neither supports the password grant type. The password grant type (ResourceOwnerPasswordCredentialsGrantType) is not enabled for any client. The server only supports authorization_code, refresh_token, and client_credentials grant types.
