'parameters' is a required property in the specified configuration.

The 400 status error in the Azure OpenAI API, specifically the message indicating that 'parameters' is a required property - 'functions.0', can be attributed to several reasons:

Incorrect Request Configuration

The request may not include all the necessary properties or fields that the API requires to process the request. In this case, the parameters property is mandatory but is missing or not properly formatted[5%.

Missing Required Properties

The API endpoint you are using may require specific properties, such as parameters, which are not included in your request payload. This omission leads to the server rejecting the request.

Invalid Request Payload

The JSON payload sent with the request might be invalid or incorrectly structured, which prevents the server from parsing it correctly. This could include missing or incorrectly named fields, such as the required parameters property.

API Endpoint and Version Issues

There might be changes in the API endpoint or version that you are using, which could introduce new requirements or modify existing ones, such as the necessity of including the parameters property.
