Troubleshooting

Problem: No tasks created although emails are labeled “To-Do.”

Cause: Label name misspelled or missing from Gmail Trigger query.

Fix: Check exact label spelling and that emails have the label. Confirm Gmail Trigger filter query is label:To-Do.

Problem: Google Tasks node shows authentication errors.

Cause: OAuth2 credential expired or missing required permission.

Fix: Reauthenticate Google Tasks OAuth2 credential with correct scopes in n8n.

• Test that Gmail Trigger captures labeled emails.
• Verify new tasks appear in Google Tasks after running workflow.
• Check OAuth2 credentials are valid and have needed scopes.
• Backup important data before fully using the workflow.
