Analyze failed workflows with Claude via OpenRouter and log to Sheets with Slack, Email, Discord alerts

Who is this for

This workflow is designed for n8n users who manage multiple production workflows and want to: Receive intelligent, actionable error alerts instead of raw stack traces Understand root causes without manually debugging every failure Prevent alert fatigue from repeated similar errors Maintain a searchable log of all workflow errors

It's ideal for animal advocacy organizations, campaign coordinators, and activists running mission-critical automation workflows for outreach, volunteer coordination, or campaign monitoring.

What it does

When any workflow in your n8n instance fails, this agent automatically: Captures the error details including workflow name, failed node, error message, and stack trace Uses AI (via OpenRouter/Claude) to analyze the error and suggest root causes and fixes Generates a unique error signature for deduplication Logs the error with AI analysis to Google Sheets for historical tracking Checks for recent duplicate errors to prevent alert fatigue Sends enriched notifications through your choice of Slack, Discord, Email, or Webhook

The AI analysis includes root cause identification, error chain tracing, specific fix recommendations, and a confidence score indicating how certain the analysis is.

How to set up

Import the workflow into your n8n instance Configure credentials for: OpenRouter API for AI analysis Google Sheets for error logging Notification channels you want to use (Slack, Discord, Gmail, or Webhook URL) Create a Google Sheet with columns matching the log fields Update the receiver email addresses in the "Normalize Error Payload" node Enable the workflow Set this workflow as the error handler for other workflows you want to monitor

Requirements

OpenRouter API key (for AI-powered error analysis) Google Sheets OAuth2 credentials At least one notification channel configured (Slack, Discord, Gmail, or custom webhook) n8n instance with Error Trigger capability

How to customize

Change the AI model**: Edit the OpenRouter Chat Model node to use a different LLM Adjust alert fatigue settings**: Modify the lookback count and time window in the "Check Alert Fatigue" code node Switch logging backend**: Replace the Google Sheets node with PostgreSQL, Notion, or any other storage Add notification channels**: The workflow sends to multiple channels in parallel - add or remove as needed Customize email recipients**: Update the receiver emails array in the normalize payload node
