How It Works ⚙️

1. 🚨 A Workflow Fails: When any workflow in your n8n instance encounters an error, this workflow is automatically triggered. 2. 🧠 AI Analysis: The Error Trigger node passes the complete error context (message, stack trace, failing node, etc.) to a LangChain Agent. The agent is prompted to perform a deep analysis, identifying the root cause, potential solutions, impact, and urgency. 3. ✨ Format Data: A Set node neatly organizes the original error details alongside the new, structured AI analysis into a single, clean data object. 4. 📧 Send Detailed Report: The Gmail node uses this formatted data to construct a rich HTML email, presenting the error details and the AI's full analysis in a clear, actionable format, and sends it to your specified address.
