Workflow Failure
Workflow: Code Scanning Fixer
Branch: main
Run: https://github.com/github/gh-aw/actions/runs/37129527280
Warning
Repeated Permission Denied: The agent was denied permission to run 1 command(s) and stopped retrying.
Denied Commands:
shell(python3 - <<'E' | shell(go build ./pkg/workflow/ && git diff --binary --no-ext-diff | wc -c) | shell(cat > /tmp/gh-aw/agent/pr.json <<'E'How to fix this
The agent ran in non-interactive mode (
--no-ask-user) and could not request permission at runtime.To resolve repeated permission denied errors, update the workflow prompt to avoid these commands or use approved alternatives. Use the following prompt with any coding agent:
Warning
Engine Failure: The
copilotengine terminated unexpectedly.Last agent output:
