Resolving OpenAI ‘$.input’ is Invalid Error: A Step-by-Step Guide


Encountering the ‘$.input’ is an invalid error in OpenAI? Then, Learn how to fix it step-by-step with this informative guide. Discover how converting arrays to JSON format can resolve this issue and get your OpenAI integration back on track.

Are you facing the ‘$.input’ is invalid error while using OpenAI, particularly with models like text-embedding-ada-002?

Don’t worry; you’re not alone. This error typically arises when sending input data in a format that OpenAI’s API doesn’t recognize. Fortunately, there’s a straightforward solution to this problem.

Understanding the Error Understanding the Error

When you encounter the error message similar to the following:

stdClass Object
    [error] => stdClass Object
            [message] => '$.input' is invalid. Please check the API reference:
            [type] => invalid_request_error
            [param] => 
            [code] => 


It indicates that the input data you’re providing to the OpenAI API is not in a recognized format, leading to an invalid request error.

Solution: Converting Array to JSON Format Solution: Converting Array to JSON Format

If you’re using PHP, like many developers, and encountering this error, it’s likely due to sending input as an array. To resolve this, you need to convert the array to JSON format before passing it to the OpenAI API.

Here’s a step-by-step guide to implementing the solution:

  1. Identify Input Data: Determine the input data you’re passing to the OpenAI API, whether it’s a single string, an array of strings, an array of integers, or an array of arrays containing integers.
  2. Convert to JSON: If your input data is an array, use PHP’s json_encode() function to convert it to JSON format. For example:
   // Original input array
   $input_text = array(/* Your input data */);

   // Convert to JSON format
   $json_input = json_encode($input_text);
  1. Update API Call: Replace the original array input with the JSON-formatted data in your API call. For instance:
   // Before
   'input' => $input_text,
  1. Test the Solution: After making these changes, test your OpenAI integration to ensure that the error no longer occurs. If everything is functioning as expected, you’ve successfully resolved the issue.
