Run a weekly n8n security audit and email changes with Supabase and Gmail

Description

How it works

If your main Error Diagnosis workflow fails for any reason, this backup workflow sends an alert email to the workflow owner.

For a (main) advanced and automated error diagnosis workflow check: ++flowcheckers.com++

Node 1 - Backup Error Trigger
No configuration needed. Fires automatically when the main workflow encounters an unhandled error.

Node 2 - Internal alert notification
Sends an alert email to the workflow owner when the main diagnosis workflow fails. The email contains the error details, the workflow name, and a link to the failed execution in n8n so the owner can investigate immediately.

Setup
Import backup-error-workflow.json into your n8n instance
Connect the Resend credential inside the Resend node (Important: the From address must be a domain verified in Resend, otherwise the send will be rejected)
Link this workflow as the Error Workflow of the main diagnosis workflow
Confirm the workflow is saved
