Fix Node API Endpoint Bug

Job ID: 40542361

Budget: £20 – £250 GBP

A single POST endpoint in my Node API is failing on specific requests. Other routes behave normally, so I know the server and database layers are healthy—the problem sits squarely inside that endpoint’s logic or its validation chain.

What I need:
• Trace and identify the exact cause of the API endpoint error that appears only when certain POST requests hit the route.
• Patch the code so the endpoint returns the correct response every time, with appropriate error handling for edge-case payloads.
• Provide a concise summary of the fix (files touched, lines changed, root cause) so I can track it in version control.

The project is complete when the offending POST route responds with the expected status and body on all test cases without introducing regressions anywhere else in the Node application.
