This n8n workflow is designed to automatically notify users of errors in their workflows, ensuring prompt attention and resolution. It triggers when any monitored workflow encounters an error and sends detailed alerts via multiple communication channels.

Here’s how it works:

1. The workflow includes a Sticky Note labeled ‘ERROR ALERTER’ for easy identification.

2. When an error occurs, the ‘Error Trigger’ (currently disabled) can activate the process, or it can be triggered through another workflow via the ‘When Executed by Another Workflow’ node.

3. A ‘Prepare Messages For Notify’ node runs custom JavaScript code that extracts error details—such as the workflow name, node, error message, description, timestamp, and URL—and formats this information into a structured, easy-to-read message.

4. The system then dispatches notifications through various channels: Gmail, WhatsApp, Telegram, Discord, and Slack. Nodes for Gmail, WhatsApp, Discord, and Slack are set up but disabled; the Telegram notification node is active.

5. To set up this error notifier, users need to activate the relevant nodes and configure credentials for each communication service.

This workflow is especially useful in production environments where continuous monitoring of automated processes is critical. It ensures that administrators are immediately informed of issues, allowing for swift troubleshooting and minimal downtime.
