Invalid input detected. Please check the API reference for correct usage: https://platform.openai.com/docs/api-reference.

The 400 status error in the Azure OpenAI API, specifically the message '$.input' is invalid. Please check the API reference: https://platform.openai.com/docs/api-reference., indicates that the request made to the API is not properly formatted or configured. Here are some reasons why this might be happening:

Invalid Request Syntax

The API request may contain invalid syntax or incorrect formatting in the request body or parameters, which the server cannot understand.

Incorrect Payload

The payload passed to the API might be incorrect or not conform to the expected schema. This includes issues with the messages array or other required fields in the request body.

Missing or Incorrect Headers

The request might lack necessary headers, such as the API key or correct content type, or the headers might be incorrectly formatted.

Rate Limiting or Throttling

Although less likely to cause a 400 error directly, hitting rate limits could lead to malformatted error responses if not handled properly.

Incorrect Resource URI or Endpoint

The URL or endpoint used in the request might be incorrect or malformed, leading to a 400 error response.

These issues collectively point to a problem with how the request is structured or the data it contains, resulting in the server being unable to process it.
