About this gig

Your n8n workflow throws an error and you're stuck? Send it to me and get it fixed within 24 hours, with a written explanation of what was wrong. No calls, everything in chat.


Typical things I fix:

  • "Cannot read properties of undefined", broken expressions like {{ $json.field }}
  • Nodes returning empty output, wrong item linking, pagination that stops early
  • Credential/OAuth errors, webhooks not firing, schedules running at the wrong time
  • Code node (JavaScript/Python) bugs, JSON parsing, date and timezone mess
  • Workflows that worked before an n8n update and now don't


How it works:

  1. You send the workflow JSON (Download) plus a screenshot of the error
  2. I reproduce it, fix it and send back the corrected JSON with a short note on the cause
  3. You import it and run it. One revision included if anything is still off
