Invalid schema for function 'matching_auto_reply': The provided data type is not valid under the defined schemas.

The 400 status error in the Azure OpenAI API, specifically the "Invalid schema for function" error, can be triggered by several reasons:

Invalid or Missing Schema

The error indicates that the JSON schema provided for the function is incorrect or missing required items. For example, the items array schema might be missing or incorrectly defined.

Incorrect Request Payload

The payload sent to the API may not conform to the expected JSON schema. This could be due to incorrect formatting, missing required fields, or using unrecognized request arguments.

Model-Specific Parameters

Different models in OpenAI have specific parameter requirements. For instance, some models may require max_tokens while others need max_completion_tokens, and using the wrong parameter can lead to errors.

Data Type Mismatch

The error message " 'float' is not valid under any of the given schemas" suggests that there is a data type mismatch in your request payload. This means the data type of one or more fields in your request does not match the expected schema defined for the function or model you are interacting with.

Header and Content-Type Issues

Incorrect headers, particularly the Content-Type header not being set to application/json, can also result in a 400 error as the server expects a specific format that is not being provided.
