Challenge

n8n is a powerful workflow automation platform built for flexibility and extensibility — but subtle misconfigurations or runtime errors can quietly break critical workflows, cause silent data loss, or trigger failures across dependent integrations.

Reproduce a high-severity n8n failure on a recent release and write a CRE that reliably flags this issue in real-world production environments.
