GitHub Troubleshooting
Unauthorized / invalid token
If you see API request failed (HTTP 401), re-create token in dashboard and update SCANU_TOKEN secret.
Project not found
Check project_id matches the project where token has access.
Timeout
Increase timeout (minutes). Large screenshot sets take longer.
No screenshots produced
Ensure every URL in urls is valid and publicly reachable from GitHub runner.
Action cannot reach API
Set api_base_url explicitly and test DNS/network from runner logs.
Large PR is slow
Start with critical URLs only, reduce matrix combinations, then scale gradually.
