{"agent":"claude","input":"A Datadog monitor on this Express service fired; its webhook payload follows this prompt. Use the Datadog connection to read the monitor and the error logs and APM traces from the 30 minutes around the alert. Use the traces' route resource to find the handler in src/app/routes/article/article.controller.ts and the service function in article.service.ts that produced them, and check how the error middleware in src/main.ts reported it. Write a Jest regression test in src/tests/services/ using the Prisma mock in src/tests/prisma-mock.ts, fix the code, run npm test, and open a pull request that quotes the log lines the fix addresses and links the monitor. If the cause is not in the code, open no pull request and say what you found.\n\nMonitor payload:\n{payload}","resources":[{"url":"https://github.com/your-org/your-app"}],"connections":["datadog"]}
