When a node fails in any connected workflow, the Error Trigger captures the event. It filters out self-loops to prevent recursion. The system then fetches the original workflow\u2019s JSON and passes it to an AI Agent. The AI diagnoses if the failure was a transient network error (RETRY) or a configuration mistake (FIX). Based on this, it either waits and retries the execution or uses a Code Node to dynamically patch the JSON and update the workflow via the n8n API.\n\n### Setup Required:\n\nGlobal Error Workflow: Set this workflow as the \"Error Workflow\" in your other workflows' settings.\n\nn8n API Credentials: Create an API Key in n8n and link it to the HTTP Request nodes.\n\nAzure OpenAI: Configure the Azure Open AI credentials.\n\nSlack: Connect your Slack account and update the Channel IDs to receive real-time repair notifications."
