🚀 EXPERT n8n WORKFLOW DEBUGGING & REPAIR
Need your n8n workflow fixed fast? I run multiple production n8n
instances on my own infrastructure and debug complex workflows daily.
Whether your automation broke after an update, your webhooks aren't
firing, or your API calls return errors — I'll diagnose the root
cause and deliver a working fix.
✅ WHAT I FIX
- Broken HTTP Request nodes (auth, headers, pagination, body format)
- Webhook timeout and retry collision issues
- Expression syntax errors ({{ $json }} vs {{ $('Node').item.json }})
- SplitInBatches / Loop misconfigurations
- Conditional logic (IF / Switch) returning wrong branches
- Credential issues after n8n version upgrades
- Telegram, WhatsApp, Slack, Discord bot integrations
- Google Sheets / Airtable / Notion sync problems
- OpenAI / Anthropic Claude API integration errors
- Custom JavaScript code in Function nodes
- Self-hosted n8n deployment / Docker / reverse proxy issues
✅ MY PROCESS
1. Share your workflow JSON export and error screenshot
2. I import it to my own n8n setup and reproduce the issue
3. I identify the root cause and prepare a clean fix
4. I send you the fixed JSON with a brief explanation
5. You import it back — your existing credentials reconnect
automatically. Done.
For complex cases, I also offer 15-minute screen share calls.
