FAQ
Can you fix a workflow that suddenly stopped working?
Yes. I'll inspect the failed execution, identify the likely cause, repair the agreed issue and test the affected workflow path.
Can you fix an n8n webhook that receives no data?
Yes. I'll check the webhook URL, HTTP method, workflow activation, incoming request and response configuration. The fix depends on where the request is failing.
Can you fix HTTP 401, 403, 404 or 429 errors?
Yes. I can investigate authentication, permissions, endpoint URLs and rate limits. Some issues require changes or approval from the external API provider.
Can you repair incorrect JSON or missing fields?
Yes. I can inspect the incoming and outgoing data, expressions and node mappings to find why fields are missing or incorrectly formatted.
Can you debug OpenAI or AI agent nodes in n8n?
Yes, within the agreed scope. I can troubleshoot API connectivity, credentials, input/output mapping, tool connections and workflow logic.
Will you test the workflow after fixing it?
Yes. I'll test the affected path using available sample or approved test data and report any remaining external blockers.
Do you build new n8n workflows from scratch?
This gig focuses on debugging and repairing existing workflows. A new build or major redesign can be quoted separately.
What if the problem cannot be fixed?
I'll explain what the diagnosis reveals and identify any external limitation, such as missing API permissions, provider downtime or unavailable functionality. A successful fix cannot be guaranteed before investigation.
Do you need my n8n login details?
Not always. Screenshots, a sanitized workflow export and error details may be enough. If access is necessary, use a secure, limited-access method and never send secrets in plain chat.
