n8n Workflow Debugging & Error Fix (Stabilization Audit)Brian Marques
diagnose and fix broken or unreliable n8n workflows and improve stability so your automations run consistently.
This service is ideal if your workflow is failing intermittently, duplicating actions, breaking on API responses, or becoming difficult to maintain.
What I do
Investigate workflow failures and identify root causes
Fix broken logic, mappings, conditions, and node configurations
Resolve webhook/API issues (payloads, auth, response formats)
Improve reliability with retries, validation checks, and safer flow logic
Clean up workflow structure for maintainability
Typical issues I fix
Duplicate runs / repeated sends
Broken JSON mappings
Webhook payload parsing problems
API authentication/token issues
Incorrect branching/conditions
Timeout / sequencing / edge-case failures
Deliverables
Fixed or improved n8n workflow
Summary of issues found + changes made
Reliability recommendations (when relevant)
Basic handoff notes for future maintenance
What I need from you
Brief description of the issue / expected behavior
n8n workflow export or access (if possible)
Error logs / screenshots (if available)
APIs/tools involved
Sample payload or example failing run (optional but helpful)
FAQs
Yes, I often debug inherited workflows and improve reliability without rebuilding from scratch.
Yes, I handle webhook payload mapping, API auth, response parsing, and flow logic issues.
Yes, I include a clear summary of the root cause(s) and what I changed.
I’ll tell you upfront and can propose a cleaner rebuild if patching isn’t the best option.
