This PR handles the error that's making crashlooping in prod. We just crash if the queue message has not the right format

Also, prints some useful info on which part throws an error

Walkthrough

The changes introduce improved error handling and robustness to the message processing flow in the Telegram app's main module. A new helper function, parseNewMessage, is added to safely parse incoming messages, logging errors and returning null if parsing fails. The onNewMessage function is updated to utilize this helper and includes additional error handling when retrieving subscriptions. The message consumer is also updated to log any asynchronous errors during message processing.

Changes

File(s) Change Summary
apps/telegram/src/main.ts Added parseNewMessage for safe message parsing; updated onNewMessage with improved error handling and early returns; updated message consumer to log async errors.

Poem

A message arrives, what could it be?
Now parsed with care, as safe as can be.
If errors appear, we log and we learn,
No more surprises at every turn.
With each new hop, our code grows strong—
Robust and ready, it hops along! 🐇✨

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
