Input content is not of the expected type 'object'.

The 400 status error in the OpenAI API, specifically the message {"role":"user","content":"What\'s a Fractal?"}' is not of type 'object' - 'messages.0', indicates that there is an issue with the format or structure of the request data.

Here are the key reasons for this error:

Invalid Data Type

The error message suggests that the messages field, which is expected to be an array of objects, contains an item that is not an object. In this case, {"role":"user","content":"What\'s a Fractal?"} is likely not formatted correctly or is missing some required fields that make it a valid object within the messages array.

Request Syntax or Configuration

The server could not understand the request due to invalid syntax or configuration. This often includes issues like incorrect or missing fields in the request body, or the request not adhering to the expected API schema.

Validation Errors

OpenAI's API has strict validation rules for the data sent in requests. Any deviation from these rules, such as missing required fields or incorrect data types, will result in a 400 error.
