fix: prevent internal error.message leakage in incidents webhook handler

[tmdeveloper007]

Summary

Fixes an internal error detail leakage vulnerability in the incidents webhook handler. In production (NODE_ENV !== "development"), the raw error.message is no longer returned to clients. Only a generic "Internal server error" message is exposed.

Issue

Addresses error message exposure in app/api/integrations/incidents/webhook/route.ts.

Changes

• Changed error handler to check process.env.NODE_ENV before returning error details
• In development: full error.message is returned (for debugging)
• In production: returns "Internal server error"
• Full error is still logged to server console for debugging

Security Impact

Prevents internal error details (stack traces, file paths, dependency versions) from being exposed to unauthenticated webhook callers in production.

Files Changed

• app/api/integrations/incidents/webhook/route.ts

Warning

Review limit reached

@tmdeveloper007, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 55 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
