I will fix and debug your broken n8n workflow

Your n8n workflow was working. Now it is not and the error message is not telling you much.

I fix broken n8n workflows: failing HTTP nodes, webhooks that stopped firing, authentication that

expired, JSON that does not match what the next node expects, loops that silently drop items, and

executions that succeed while doing nothing.

WHAT YOU GET

- The root cause explained in plain language, not just a patched node

- The workflow fixed and tested end to end

- A short note on what broke and how to stop it recurring

HOW I WORK

I reproduce the failure before changing anything. A fix I cannot demonstrate is a guess, and

guesses in automation tend to come back a week later.

ABOUT ME

Software engineer working on AI automation and multi-agent systems full time. I build workflow

automation and MCP tooling for a global engineering company, and contribute fixes to open-source

Python projects including qdrant/fastembed.

Message me with the error and a screenshot of the workflow before ordering and I will tell you

honestly whether it is a 20-minute fix or something larger.
