I will fix n8n workflow errors, webhooks, and API issues


About this gig
Is your n8n workflow failing, stopping at one node, missing data, or returning the wrong result?
I will inspect the actual execution, isolate the root cause, and deliver either a clear diagnosis or a verified repair.
I can help with:
- Failed nodes and workflow executions
- Webhook and HTTP Request errors
- REST API, OAuth, and credential issues
- Expressions, JSON, and field mapping
- Missing, duplicated, or malformed data
- AI Agent, Chat Model, and Tool connection errors
- Docker and self-hosted n8n problems
Choose Basic for a written root-cause diagnosis. Choose Standard to repair one primary failure in one workflow. Choose Premium for several related failures or a structured handoff.
Every repair includes a safe acceptance test. I do not mark a workflow as fixed without evidence.
Message me before ordering with your n8n version, failed node, exact error, and expected result. Remove passwords, API keys, tokens, and private customer data from all files.

FAQ
Does Basic include repair?
No. Basic provides the root cause, evidence, repair scope, and acceptance test. Select Standard or Premium for implementation.
Can you work with self-hosted n8n and Docker?
Yes. Provide the n8n version, hosting method, relevant logs, and a redacted environment description.
Can you fix OAuth or credential errors?
I can diagnose and guide the configuration. You complete passwords, verification codes, and authorization inside your own account.
Can testing trigger production actions?
Only after risks are identified and a safe test is agreed. No real message, post, payment, or destructive data change is triggered without explicit authorization.
