⚡ Who Is This For?

Operations Teams: Maintain uptime and swiftly troubleshoot errors across multiple workflows.
Small to Medium Businesses: Gain professional error alerting without expensive monitoring tools.
Automation Enthusiasts: Enhance your automation reliability with real-time failure notifications.

❓ What Problem Does It Solve?

This workflow embedd error detection and notification directly within your n8n instance. It automates the process of catching errors as they occur, compiling meaningful context, and delivering it instantly via your preferred messaging platforms. This drastically reduces your response time to issues and streamlines error management, improving your automation reliability and operational confidence.

🔧 What This Workflow Does

⏱ Trigger: Listens for any error generated in your n8n workflows using the n8n Error Trigger node.

📎 Step 2: Executes a Code node that formats a detailed error message capturing workflow name, error node, description, timestamp, and an execution URL.

🔍 Step 3: Sends the formatted error notification to multiple communication channels: Telegram and Gmail by default, plus optionally Discord, Slack, and WhatsApp (disabled by default).

💌 Step 4: Delivers rich, parsed HTML-formatted messages to ensure error readability and immediate actionability.
