This may lead to a less comprehensive review. WalkthroughAdds try/catch around JSON.parse of the MONGO_OPTIONS environment variable in MongoDB configuration; on parse failure the code throws a new Error with a diagnostic message and the original error as the cause, aborting startup.

In @.gitignore:
- Around line 44-45: The .gitignore modifications are unrelated to the
MONGO_OPTIONS error handling work; revert the changes in the .gitignore file
(specifically remove the added entries "yarn.lock" and "deno.lock") or move them
into a separate PR for independent review; ensure "yarn.lock" remains tracked in
git (do not ignore it) so reproducible builds with yarn@4.11.0 are preserved and
only unrelated ignore edits are excluded from this branch.
In @apps/meteor/packages/rocketchat-mongo-config/server/index.js:
- Around line 30-39: The catch block currently logs the raw mongoOptionStr which
may expose secrets; change the error logging in the catch to avoid printing the
full environment variable: remove or replace the console.error('Value:',
mongoOptionStr) with a redacted representation (e.g., a helper like
redactSensitive(mongoOptionStr) or log only length and first/last N chars or a
fixed masked string), keep the descriptive error and error.message, and ensure
mongoConnectionOptions and mongoOptions handling remains unchanged so the
function still throws the Invalid MONGO_OPTIONS error after logging the redacted
context.
- Line 36: The console.error call is exposing sensitive MongoDB configuration by
printing mongoOptionStr; remove or sanitize this output. Replace the direct
console.error('Value:', mongoOptionStr) usage in the code that constructs or
logs mongoOptionStr with either no value at all (only a generic message) or a
redacted version (mask credentials/hosts/params) before logging; ensure the
change targets the console.error invocation that references mongoOptionStr so no
raw connection data is emitted to logs.

34-38: Consider consolidating error logging.The multiple
console.errorcalls could be consolidated into a single structured log message for better maintainability and observability.♻️ Optional refactor
- console.error('Failed to parse MONGO_OPTIONS environment variable.'); - console.error('Error:', error.message); - console.error('Value:', mongoOptionStr); - console.error('Please ensure MONGO_OPTIONS contains valid JSON.'); + console.error('Failed to parse MONGO_OPTIONS environment variable:', { + error: error.message, + valueLength: mongoOptionStr.length, + guidance: 'Please ensure MONGO_OPTIONS contains valid JSON.' + });

- Line 35: The code currently logs and re-throws JSON.parse() error.message (in
the MONGO_OPTIONS parsing block), which can leak sensitive substrings from the
MONGO_OPTIONS value; change the console.error call to log a generic message like
"Failed to parse MONGO_OPTIONS" (do not include error.message or the raw input)
and change the thrown error to a non-sensitive message such as "Invalid
MONGO_OPTIONS" or rethrow a new Error with a generic description; locate the
JSON.parse usage that references MONGO_OPTIONS and update both the console.error
and the throw statements (remove any direct usage of error.message or the raw
MONGO_OPTIONS content).

30-38: Simplify the error message to reduce redundancy.The error message on line 37 repeats information already conveyed by the exception type and log output above it:
♻️ Suggested improvement
- throw new Error('Invalid MONGO_OPTIONS environment variable: JSON parse failed. Check the value is valid JSON.', { cause: error }); + throw new Error('Invalid MONGO_OPTIONS: must be valid JSON', { cause: error });The try-catch pattern, diagnostic logging, error cause chaining, and Node.js version compatibility are all sound.

28-29: LGTM: Proper gating for optional environment variable.The check correctly handles the case when
MONGO_OPTIONSis undefined, ensuring the parsing logic only runs when the variable is explicitly set.
34-36: Good observability: diagnostic logging aids debugging.The diagnostic messages clearly identify the failure, provide the value length (avoiding secret leakage), and offer actionable guidance. This will significantly improve debugging in production environments.

@ggazzo @sampaiodiego can you guys please give this pr a go, it took alot of time to find this unique problem, think of a solution, and then make it work enough to fit RocketChat standard as well as fix all the issues reviewed by coderabbit as well, i would really appreciate feedback on this |

@ggazzo @sampaiodiego can you guys please review this pr guys |

@sampaiodiego Thanks alot, I have now implemented every suggestion that you had, please review the changes and recommend any further changes if need be, Thank You! |
|
hey @smirk-dev , I'm sorry I just realized I've made a typo on my previous comments where I said "related changes" I actually meant unrelated changes. so I noticed you're still adding a lot of unrelated changes, I'd ask again to remove all unrelated changes and keep only the changes on the file |
|
Thank you for the clarification, @sampaiodiego. I apologize for the confusion and the unrelated changes that were included. I have now removed all unrelated changes from this PR. The only files modified are:
The implementation now simply wraps the JSON.parse in a try-catch and throws a clear error with the original error preserved via the try {
const mongoOptions = JSON.parse(mongoOptionStr);
Object.assign(mongoConnectionOptions, mongoOptions);
} catch (error) {
throw new Error('Invalid MONGO_OPTIONS environment variable: must be valid JSON.', { cause: error });
}This follows your feedback to keep the error message concise without verbose logging, while still preserving the original error details for debugging. Please let me know if there's anything else that needs to be addressed. |

Thank you for the review feedback, @sampaiodiego.
I have addressed all your comments in commit 3279e3f:
1. Verbose logging (index.js): Removed all console.error statements. The error handling is now a simple throw with the cause property:
throw new Error('Invalid MONGO_OPTIONS environment variable: must be valid JSON.', { cause: error });2. Unrelated changes: Removed all unrelated files from the PR:
- ✅ Reverted .gitignore changes
- ✅ Removed deno.lock changes
- ✅ Removed yarn.lock changes
- ✅ Removed CLAUDE.md
The PR now only contains the MONGO_OPTIONS error handling fix in apps/meteor/packages/rocketchat-mongo-config/server/index.js and the required changeset file.
Please let me know if there's anything else that needs attention.

I'm sorry @smirk-dev but did you understand the changes we asked for? I'm trying to understand what is going on and why so much back and fourth |

I apologize @sampaiodiego and @KevLehman, i have removed every file, and made sure only to keep the 2 files that have related changes, i do not mean to spam or drag out the pull request more than it needs to, i have removed every unrelated change, but it still shows 4 files changed despite me removing deno.lock and yarn.lock, i am attaching a screenshot |

Wrap JSON.parse() in try-catch to prevent application crash on startup when MONGO_OPTIONS environment variable contains invalid JSON. The error now includes the original error as cause for debugging while maintaining fail-fast behavior on startup. Fixes RocketChat#38100

This is a low-risk change that only adds error handling around existing code. The fix follows standard error handling patterns and improves operational debugging without changing any functional behavior for valid configurations.
