In this video, we explore the essential topic of Error Workflows in n8n, an often overlooked yet crucial feature for managing workflow failures. Learn how to create a reusable error workflow that triggers when a workflow fails, sending an email with detailed error information. We’ll walk you through setting up a simple workflow, introducing an error, and creating an error workflow to notify you instantly. Plus, discover how to extend this workflow to send alerts via Slack, Discord, or store messages in a database. Perfect for anyone looking to enhance their n8n automation setup with robust error handling. 🙏 Support My Channel: Buy me a coffee ☕ : https://www.buymeacoffee.com/leonvanzyl PayPal Donation: https://www.paypal.com/ncp/payment/EKRQ8QSGV6CWW 📑 Useful Links: n8n Cloud Affiliate Link: https://n8n.partnerlinks.io/f7f19w3vrhin n8n Tutorial Playlist: https://www.youtube.com/playlist?list=PL4HikwTaYE0GrWQOYuTL3YvHLMMwOjn7O 🧠 I can build your chatbots for you! https://www.cognaitiv.ai 🕒 TIMESTAMPS: 00:00 - Introduction to n8n Error Workflows 01:18 - Setting up our main workflow 02:46 - Creating the error workflow 03:29 - Setting up Gmail 08:33 - Formatting Email body 09:28 - Assigning Error Workflow
