Invalid data type: expected a 'string' for the field 'user' but received a different type.

The 400 status error in the Azure OpenAI API, specifically the error message "1719 is not of type 'string' - 'user'," can be caused by several factors:

Invalid Data Type

The error indicates that the value provided for the 'user' field is not a string, which is the expected data type. This could be due to incorrect formatting or an incorrect data type being passed in the request payload.

Incorrect Request Configuration

The request payload might not be properly formatted or might contain invalid syntax. For example, the messages array or other required fields might not be correctly structured or might contain non-string values where strings are expected.

Payload Size or Content Issues

The data payload could exceed the maximum allowed size or might contain content that violates OpenAI's content management policies, leading to the server rejecting the request.

Missing Required Properties

The request might be missing necessary properties or fields that are required for the API to process the request correctly. For instance, the content field could be missing or incorrectly formatted.

These issues collectively point to a mismatch between the expected request format and the actual request sent to the API.
