Workflow Failure

Workflow: Runtime Failure Observer (xharness)
Branch: main
Run: https://github.com/dotnet/xharness/actions/runs/33392187903

Warning

Missing Data Reported: The agent reported missing data during execution.

Missing Data:

• Helix console log: The required console request for failing work item System.Diagnostics.Tools.Tests in Helix job c751ae0a-9c9c-4ae7-b20e-f7e9cec01cd0 returned HTTP 404, so xharness evidence cannot be assessed.
  • Alternatives: Rerun the observer against a build whose Helix console remains available.

Warning

Engine Failure: The copilot engine terminated unexpectedly.
