{"agent":"claude","input":"A Datadog monitor on this FastAPI service fired; its webhook payload is at the end of this prompt. Use the Datadog connection to read the monitor, the error logs and the APM traces for its service and environment from 15 minutes before to 15 minutes after it fired. Group the errors by exception and the innermost frame in this repository, map each trace's route template to its router in backend/app/api/routes, and find the code path that produced them. Start the database the tests need, apply the Alembic migrations, and write a pytest regression test with the existing TestClient and token fixtures that sends the request the traces show and fails for the same reason. Fix the cause, run the full backend test suite, and open a pull request that quotes the log lines and trace ids the fix addresses. If the cause is not in this code, change nothing and answer with what the logs show.\n\nPayload: <Datadog webhook body>","resources":[{"url":"https://github.com/your-org/your-app"}]}
