n8n errors / Auth

Node has no access to credential

platform: n8n / category: Auth

Cause

A workflow was exported from one instance/user and imported into another; the credential IDs in the JSON no longer match any credential on the new instance.

Fix

After importing, open every flagged node and re-select or recreate the credential from the dropdown — do not copy credential IDs across instances. For multi-instance setups, export credentials with 'n8n export:credentials' and import them on the target before importing workflows.
