About this gig

Is your n8n workflow broken, failing, or not running as expected?


I will debug and fix your n8n automation bugs, broken workflows, API integration errors, OAuth authentication issues, and webhook problems so your existing automation can work as intended.


If your n8n workflow is stuck, a node is failing, an API request returns an error or a webhook is not triggering, I repair everything fast.


Common n8n Errors I Fix:

  • Webhook & Trigger Failures: Webhooks not firing, missing signatures, or timing out under heavy loads.
  • OAuth 2.0 & API Authentication: Token expiration loops, 401 Unauthorized errors, and 24-hour re-invalidation issues.
  • Execution & Performance Bugs: 504 Gateway Timeouts, HTTP Request node 30s timeouts, or self-hosted Redis queue saturation.
  • Data & Mapping Errors: Resolving "Cannot read property of undefined" expressions and fixing broken workflows caused by upstream JSON payload changes.
  • Custom Code Debugging: Fixing JavaScript (Code node) or Python logic syntax bugs inside your automation.
