Fix Broken n8n Business Workflow

Everything in my current n8n automation has stalled—data never enters correctly, processing nodes crash, and nothing gets sent out the other end. Triggers refuse to fire, manual runs throw execution errors, and the whole flow is now unusable. The workflow’s purpose is broad: it automates repetitive tasks, integrates several external services, and performs key data transformations for daily operations.

I’ll give you access to the existing instance and the original .json flow. What I need back is a stable, well-commented workflow that reliably restores data input, processing, and output across all connected services.

Deliverables
• Diagnosis report outlining the root causes
• Repaired n8n workflow file, ready to import
• Brief hand-off document describing changes and any new credentials or environment variables required

Experience with webhooks, API credentials, Function/Code nodes, and error handling inside n8n will be essential. A quick turnaround is important because this automation sits at the heart of my business operations.
