Hey this implementation is incorrect, I would suggest making use of schemas.SecretVar and then using the GetValue function
https://github.com/maximhq/bifrost/blob/dev/core/schemas/secretvar.go
There was a problem hiding this comment.
Reworked onto schemas.SecretVar as suggested: UnmarshalJSON now goes through IsSecretRef → NewSecretVar → GetValue(), so vault. references work too. BaseURL stays a string at runtime (~250 read sites unchanged); the originating SecretVar is kept on an unexported field so MarshalJSON round-trips the reference instead of the resolved URL, matching CACertPEM. The unset-variable test now sets and explicitly unsets the variable so it no longer depends on the host environment. Pushed as a single commit rebased on current dev.

network_config.base_url is documented alongside the other secret-shaped fields (provider keys, ca_cert_pem) but its "env." indirection was never actually wired up: an env.-prefixed base_url is passed through verbatim and dialed as a literal hostname string, so a deployment referencing a committed-safe env var name silently fails to connect instead of resolving it. Make NetworkConfig.BaseURL a *schemas.SecretVar, the same shape CACertPEM and ProxyConfig.URL already use, so "env." and "vault." references resolve through SecretVar.UnmarshalJSON and MarshalJSON emits the reference (via SecretVarAsString) rather than the resolved URL. Every read site now goes through BaseURL.GetValue(). The per-provider default/trailing-slash handling in the constructors is folded into one providerUtils.NormalizeBaseURL helper that clones the SecretVar before trimming, so a pointer shared with a config-store copy is never mutated in place and the reference survives. A reference that resolves to an empty value is a fail-loud config error rather than an empty-host dial: a misconfigured key returns 401s, but a misconfigured base_url dials an unintended target. Callers updated: every provider constructor and read site, the provider HTTP handler's URL validation, the ollama/sgl key-backfill migration (which now carries the reference into the key URL SecretVar instead of the resolved value), the llmtests account, and the affected tests. config.schema.json documents the reference form for base_url and drops "format": "uri", which a reference would not satisfy. Signed-off-by: Valentin Yanakiev <valentin.yanakiev@gmail.com>
The server-side NetworkConfig.base_url is now a SecretVar, so "env.VAR_NAME" and "vault.path" references resolve at load time. The provider forms still rejected them: the network-config zod schemas required a URL, the provider form refined on a ^https?:// regex, and the custom-provider sheet used .url(). Add one shared isValidBaseURL predicate (http(s) URL or a non-empty env./vault. reference) with a matching message, expose it as baseURLSchema, and use it at all four sites. The base URL inputs gain a description saying a reference is accepted. The wire form stays a string, so no payload or type changes. Signed-off-by: Valentin Yanakiev <valentin.yanakiev@gmail.com>
…nd logs Two follow-ups from review of the *SecretVar base_url: NetworkConfig.Redacted copied the BaseURL pointer unchanged, so the redacted copy shared it with the original and exposed the resolved value of an env./vault. reference through GetValue. Clone it, and mask the resolved value when it came from a reference; a literal base_url stays readable because it is not a secret and the UI displays it. The JSON form already emitted the reference either way. The Gemini batch cancel/delete/results and result-file download paths logged the full request URL at debug level, which for a reference-resolved base_url means the resolved endpoint. Add providerUtils.LoggableURL, which replaces the resolved scheme and host with the reference when base_url is secret-backed and returns the URL unchanged otherwise, and use it at those four log sites.

Make this migration reversible or mark it non-rollbackable.
The forward path creates a new key from BaseURL. The rollback only drops the added columns. It does not remove the generated key or restore the original configuration state. After rollback, a later migration run can create another default Ollama or SGL key.
Track generated rows and reverse them safely, or explicitly mark this migration as non-rollbackable. As per coding guidelines, “If a migration cannot be rolled back, explicitly flag it as non-rollbackable.”

Restore validation for literal base URLs.
network_config.base_url accepts not-a-url as a plain string. NetworkConfig.UnmarshalJSON and NormalizeBaseURL do not validate literal URLs. Ollama appends an API path and passes the malformed value to fasthttp.Request.SetRequestURI, which does not return a validation error. Invalid configuration therefore reaches request handling instead of failing during configuration validation.
Use an anyOf or oneOf that accepts valid literal URLs and the supported env. and vault. reference forms.

Summary
network_config.base_urlsits alongside config fields that already accept aSecretVarreference (ca_cert_pem,proxy.url, the Ollama/SGL key URLs), but a"base_url": "env.SOME_VAR"was never resolved: it was passed through and dialed as a literal hostname. Requests to that provider fail to connect with no diagnostic pointing at the real problem.This makes
base_urlaSecretVarlike the other reference-capable fields, so an upstream URL can be kept out of committed config the same way credentials already can.Changes
NetworkConfig.BaseURLis now*schemas.SecretVar(json:"base_url"), the same shape asCACertPEMandProxyConfig.URL.SecretVar.UnmarshalJSONhandles plain URLs,env., andvault.references;MarshalJSONemitsSecretVarAsString(nc.BaseURL), so config-store persistence,ProviderConfighashing, and API responses stay reference-shaped. No shadow field.BaseURL.GetValue(): all providers (includingdatabricksandgithub-copilot, which landed ondevafter this PR was opened), the OpenAI/ElevenLabs realtime paths, and the provider HTTP handler'sValidateExternalURLcheck.providerUtils.NormalizeBaseURL(&config.NetworkConfig, defaultURL)helper (""for ollama, sgl, vllm, databricks, and github-copilot, whose base URL is optional). It clones theSecretVarbefore trimming, so a pointer shared with a config-store copy is never mutated in place, and theenv./vault.reference survives normalization.network_config.base_url references "env.X" but it resolved to an empty value. Same fail-closed stanceConfigureTLStakes forca_cert_pem; the alternative is dialing an empty host. Surrounding whitespace in a resolved value is trimmed.SecretVarinto the key URL (reference preserved) instead of wrapping the resolved string.config.schema.json:base_urldocuments the reference form and drops"format": "uri", which anenv.reference would not satisfy. The wire form is still a string, so the UI types are unaffected.docs/quickstart/gateway/provider-configuration.mdx.NetworkConfig.RedactedclonesBaseURLand masks the resolved value when it came from a reference (literal URLs stay readable for the UI);providerUtils.LoggableURLkeeps a reference-resolved base URL out of the four Gemini batch debug logs.isValidBaseURLpredicate (http(s) URL or a non-emptyenv./vault.reference) now backs all four validation sites viabaseURLSchema, and the base URL inputs describe the reference form. Wire shape unchanged.Revision history: v1 hand-rolled

coremodule onlyNetworkConfig.BaseURLchanges type fromstringto*schemas.SecretVar; downstream Go code reads it withGetValue()and sets it withschemas.NewSecretVar(...). The JSON wire form (config.json, config store, HTTP API) is unchanged: a plain URL string still works, andenv./vault.strings that were previously dialed literally now resolve.Related issues
Found while migrating a downstream deployment (LaneTally) from
transports/v1.5.16totransports/v2.0.0.Security considerations
Lets operators keep upstream endpoints out of committed config and out of the config store, using the same reference mechanism already trusted for credentials. The resolved URL never appears in marshaled output while the reference still resolves to it.
