Debugging (workflow)
The process of identifying and fixing errors in an automation workflow. In n8n, every execution shows the exact data at each node making it easy to pinpoint where a value was lost, transformed incorrectly, or caused a downstream failure.
Expert insight
Debugging a failed workflow execution is far faster when the workflow logs the actual input and output at each step, not just a pass/fail status, "step 3 failed" tells you almost nothing, "step 3 failed because the API returned a 404 for customer ID 4821" tells you exactly where to look.
In a real workflow
An execution shows that the CRM rejected a lead because the phone number was too long, which explains the missing record.
Common mistakes
- Debugging in production with real customers.
- Not reproducing the issue before fixing it.
Complexity level
