This one needs environment variables set before it will start: RASON_BEARER_TOKEN (RASON API bearer token. Required for model management, solving, and diagnostics. Obtain at https://rason.com/.), RASON_SERVER_URL (Base URL of the RASON REST API. /api is appended automatically.), RASON_RESULT_ARRAY_LIMIT (Maximum array/dataFrame rows before solver results are summarized.), RASON_RESULT_SIZE_LIMIT (Maximum solve-result size (in characters) before truncation.), RASON_REQUEST_TIMEOUT (HTTP request timeout in milliseconds.). The author declared them in the registry entry; get the values from the project itself.
