PR Review Agents: Handling GitHub API Errors

Automated PR reviewers crash when GitHub returns a 422 error due to unmapped diff line numbers. Catching this exception and logging it ensures the rest of the review completes successfully.

What you just learned:
Catch GitHub 422 API errors on line mismatches
Log exceptions instead of crashing the review pipeline
Exit execution early if the pull request requires no review
Pause comment posting to prevent rate limits or spam

Building an AI agent for code reviews requires robust handling of the GitHub API. When line numbers fail to map directly to a pull request diff, proper error logging prevents the entire automation pipeline from failing. Handling these edge cases keeps your code review agent stable in production.
