A value is not of the expected type. Ensure that data types in the structure match the required format.

The 400 status error in the OpenAI API, specifically the message 'name' is not of type 'object' - 'functions.2', indicates that the server could not understand the request due to invalid syntax or configuration in your request payload.

Here are some possible reasons for this error:

Invalid Request Payload

The error suggests that the name field in your request is not formatted as an object as expected by the OpenAI API. This could be due to incorrect JSON formatting or mismatched data types in your request body[4/.

Incorrect Data Types

The values you are passing, such as environment variables, might be of the wrong type. For example, if the API expects numeric values but receives text, it can lead to a 400 error.

Hidden Characters or Invalid Characters

Hidden characters or invalid characters in your request, such as those that might be included when reading from environment files, can also cause the API to fail to parse the JSON body of your request correctly.

API Configuration Issues

The error could also be due to incorrect configuration of the API call, including issues with headers, base URLs, or other parameters that are not in line with the OpenAI API's requirements.
