Start with the azure:pipeline:run action in the scaffolder-backend-module-azure-devops plugin and reproduce the failure and cancellation cases described in the issue. Trace the task-run logging for unsuccessful Azure Pipeline runs; done means the action returns the pipeline status and lists pipeline errors without throwing a plugin output error.
