I Import-Tested 10 of My Own n8n Workflows on a Fresh Install. 3 Failed

Description and use

The author imported 10 n8n workflows on a fresh install; 3 failed because external service URLs were placeholders, causing silent failures.

Problem

New users import n8n workflows but fail to fully configure external service URLs, causing silent failures.

Outcome

7/10 workflows succeeded; 3 failed due to placeholder URLs or environment TLS issues.

Workflow

• Import each workflow file via n8n import:workflow
• Activate all workflows
• Create Header Auth credential and set on LLM nodes
• Set baseUrl and model in Config nodes
• Set Slack webhook URLs where noted
• Set metrics JSON endpoint
• Run each workflow once
• Verify output or Slack message
• Identify failures
• Adjust missing URLs
• Re-run failed workflows

Evidence

10 / 10 imported.

10 / 10 activated.

3 of the 10 still failed to do their job

Post to Slack still had my placeholder URL in it
