I will fix and debug your n8n workflows and API errors


About this gig
Is a broken n8n workflow, failing webhook, or API error halting your business?
When automated workflows stop running, leads drop, customer notifications fail, and teams waste hours digging through cryptic error logs. I help you find, fix, and test your n8n automations so operations run reliably again.
What I Can Fix & Troubleshoot:
- API & Auth Errors: Resolving OAuth2 token expirations, header auth issues, and 400/401/403/429/500 status codes.
- Webhooks & Payloads: Fixing malformed JSON, missing data fields, and parsing failures between applications.
- Logic & Routing: Correcting misconfigured IF, Switch, and conditional filter nodes.
- Data Processing & Looping: Resolving array mapping errors, Code node (JavaScript/Python) syntax bugs, and Split In Batches issues.
- AI & LLM Nodes: Fixing OpenAI/Claude prompt outputs, parsing errors, and agent memory issues.
How We Work Together:
- Inspect execution logs and identify failure points.
- Repair node logic and test payload flow.
- Validate safe execution without duplicate records.
Please send a message with your error message or screenshot before ordering so we can confirm the issue.

FAQ
What details do you need to start troubleshooting?
Please provide a screenshot of the failed n8n execution log, the error message or HTTP status code, and the names of the connected tools. A sanitized JSON export of the workflow also helps diagnose issues faster.
How do we securely share API keys or credentials?
Never share sensitive credentials in open messages. You can share access securely via encrypted single-use link tools (such as Bitwarden Send or 1Password) directly on the Fiverr Order page once the project begins[cite: 10].
Do you work on both n8n Cloud and self-hosted instances?
Yes. I can troubleshoot automations running on official n8n Cloud as well as self-hosted n8n setups running on Docker, VPS, or cloud servers.
Can you test the fix without affecting my live customer data?
Yes. I use isolated test payloads and sandbox environments whenever possible to ensure data isn't duplicated or sent to live customers during the debugging process[cite: 10].
What if my workflow requires a larger architectural rebuild?
If your workflow has fundamental architectural issues or needs complete multi-app reconstruction beyond a simple fix, I will clearly explain what is needed and provide a custom offer before making major changes.
