Let's find why.
A clear, step-by-step investigation of one failing n8n workflow. Understand the likely cause, what to test, and what a safe fix would involve.

SCENARIOS
TESTED
An illustrated lab trace — not a client incident.
EVIDENCE, NOT MAGIC
We tested the failure modes.
We installed real n8n locally and reproduced three deliberately broken workflows. These tests validate a repeatable method — not a proven success rate on customers' systems.
02 / RATE LIMITSLOCAL TEST
Too many requests
A simulated rate limit triggered a 429; a configured retry recovered.
429→200Retested
03 / DATA MAPPINGLOCAL TEST
Wrong payload
Incorrect field mapping produced an invalid SKU; the corrected expression passed.
400→200Retested
◇ Lab results come from synthetic inputs and a local mock API. No production integrations or paying-client repairs have been validated.

a clear path.
Not another generic workflow scanner. We are testing whether an actionable, scoped investigation can save builders time.
See if your case fitsDescribe the symptom
Share the failing node type, redacted error message and expected output. No passwords, tokens or third-party customer information.
Isolate and verify
If selected, we investigate one issue in a safe copy using representative dummy inputs and a reproducible check.

What we don't promise
Production repairs from JSON alone · recovery without access to safe logs · unrestricted data access · guaranteed outcomes for every integration.

QUESTIONS?aiventurelab@agentmail.to
NO-CHARGE RESEARCH PILOT
Request your review
We review requests individually and reply if the case fits.
Good questions.
Will you change my production workflow?
No. The free pilot is for investigation, not permission to modify a live environment. Any real implementation would need an agreed, safe scope and explicit authorization.
Should I upload my workflow JSON with credentials?
No. Do not include secrets or customer data. We may ask for a sanitized example after deciding whether your case fits.
Does the €49 price mean I can purchase a fix now?
No. €49 is a research price hypothesis, not an active checkout or a guaranteed fixed-fee repair.
Are you affiliated with n8n?
No. Workflow Triage is an independent research pilot, not an n8n company product or partner offering.
