Problems by impact
Observable behavior, likely cause, and reproduction conditions ordered by business impact.
ONE WORKFLOW / WRITTEN / NO LIVE ACCESSFind what to fix first
Find what to fix first
in one n8n workflow.
If one workflow stops, duplicates work, or reports success with the wrong output, start with the symptom. After a written fit check, share one sanitized inactive export and up to five execution examples. Receive a written diagnostic with the next repair decision.
First message: expected result, observed result, and n8n version. Do not attach files or secrets. The sanitized workflow and execution examples are requested only after fit and the sharing method are confirmed in writing.
Prefer email? Open a prefilled email. No files, credentials, or customer data first.
For: one existing workflow that stops, duplicates work, or reports success with the wrong output, when you need the next repair decision in writing.
You will receive: problems ordered by business impact, likely causes, a recommended repair sequence, and steps to verify the result.
Prepare: first message: expected result, observed result, and n8n version. After fit confirmation: one sanitized inactive export and up to five execution examples. Do not attach files or secrets to the first inquiry.
Next: inspect the public example, then use “Check whether this symptom fits” above.
WHAT YOU RECEIVEKnow what to fix first,
Know what to fix first,
and how to verify it.
The service diagnoses and recommends. It does not edit the workflow or recover production.
Likely causes
Why the input, node settings, authentication, branch, API, retry, or runtime may be responsible.
Recommended repair order
A clear sequence for what to change first and what can wait.
Verification steps
How to check the normal path and relevant retry, duplicate, invalid-input, or sustained-failure behavior.
WHAT TO SENDSanitize first.
Sanitize first.
Share later.
I do not need your production login, live credentials, or a call. Materials are requested only after scope and sharing method are confirmed in writing.
Accepted after confirmation
- One inactive workflow JSON export
- Up to five execution or error screenshots
- A short expected-versus-observed description
- An access-restricted sharing link
Remove before sharing
- Credential IDs and credential bodies
- Passwords, API keys, tokens, cookies, and signed URLs
- Personal, customer, vendor, or internal business data
- Real payloads that are not required to reproduce the issue
Working copies are deleted no later than 21 days after delivery, including when no follow-up question is submitted. If secret or personal data is received accidentally, work stops; the material is deleted and the sender is notified so affected credentials can be rotated.

- 02Confirm
I confirm fit, exclusions, sharing method, payment route, and start date in writing.
- 03Share
After agreement, share sanitized inputs through the confirmed restricted link.
- 04Receive
Get the written diagnostic and verification steps within the confirmed five-day target.
