Broken n8n Workflow Diagnosis — Root Cause + Fix Plan

Your n8n workflow is broken, unreliable, duplicating actions, or failing at an API/webhook step. Send one sanitized workflow export plus a short description of what is going wrong. You receive a focused written diagnosis for one workflow — no live production access required.

You receive:

• the most likely root cause and the evidence behind it;
• the highest-risk failure points, including retries, duplicate actions, API/webhook handoffs, error handling, and brittle logic;
• a prioritized fix plan showing what to change first;
• a bounded regression checklist so you can verify the workflow after the fix.

See the format before buying: open the synthetic sample diagnosis. It is a sample deliverable, not a customer case study.

Best fit: failed executions, intermittent failures, unsafe retries, duplicate side effects, broken data mapping, authentication/API failures, webhook handoffs, or a workflow that reports success but produces the wrong business result.

Not included: live production access, credential handling, implementation inside your instance, unlimited troubleshooting, ongoing support, or a guarantee that third-party/API failures can be eliminated.

Privacy: do not send passwords, tokens, API keys, PHI, customer records, or other sensitive data. Use redacted or synthetic evidence only.

Start the diagnosis: after purchase, open a redacted request at GitHub → Broken n8n workflow diagnosis request. Include the expected result, observed result, n8n version, and sanitized workflow JSON. Scope is one workflow per purchase.
