API Bugs

Failed to get sample code from the evals guide working. The final cURL yields this error:

{
  "error": {
    "message": "Invalid body: failed to parse JSON value. Please check the value to ensure it is valid JSON. (Common errors include trailing commas, missing closing brackets, missing quotation marks, etc.)",
    "type": "invalid_request_error",
    "param": null,
    "code": "invalid_json"
  }
}%

Here’s the cURL with valid file and eval ids for reference:
