Error Details

• Job: pre_activation
• Error message: ERR_API: Failed to fetch check runs for ref "main": route.endpoint is not a function
• Step: "Checking CI checks on ref: main (github/gh-aw)"
• Example failing run: §24000805890

Analysis

The error route.endpoint is not a function typically indicates a JavaScript SDK method call issue — either:

1. A breaking change in the @octokit/rest or @actions/github SDK
2. A recent change to the actions/setup JavaScript code that broke the check_runs API call
3. A GitHub API endpoint change

The error occurs in the CI check validation step, which calls the GitHub Checks API to verify CI status before activating.

Note: The lock file for issue-monster is also listed as stale (.md modified after .lock.yml), which may be related.

Suggested Investigation

1. Check if any recent commits changed actions/setup/js/*.cjs files, especially the check-runs logic
2. Verify the Octokit API call for check_runs in the pre-activation script
3. Compare the issue-monster.lock.yml and issue-monster.md to see what changed
4. Check if other workflows using CI check validation are also failing

Impact

Issue Monster runs every ~30 minutes. With 5+ consecutive failures, it has been non-functional for 2+ hours, missing approximately 5 issue processing cycles.
