Solutions

1. Ensure the input file passed to the script is a JSON object containing a top-level 'reviews' key.
2. Regenerate the eval output with the expected schema, or convert the existing file to the required format.

Example fix

Run: python generate_review.py eval_output.json where eval_output.json is shaped as {"reviews": [...]}.

When it happens

Trigger: The eval-viewer HTTP server receives a POST /api/feedback whose body is valid JSON but is not an object containing a 'reviews' key.

Common situations: Happens when a client posts malformed feedback to the review viewer — wrong payload shape or a stale caller. The server responds with HTTP 500 and the error message in a JSON error body.
