Invalid schema for function 'guidance_web_qna': Required fields or structure do not match the expected object or boolean types.

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

Invalid or Incorrect Schema

The error message "Invalid schema for function 'guidance_web_qna': 'bool' is not valid under any of the given schemas" suggests that the schema defined for the function does not match the data type of the parameters being passed. For example, if the schema expects an object or a specific type, but a boolean value is provided instead, it will result in this error.

Incorrect Request Configuration

The request payload or the parameters passed might not conform to the expected JSON schema. This includes issues such as missing required properties, incorrect data types, or incorrectly defined arrays and objects.

Schema Compliance

The function might be using a strict mode (e.g., TOOLS_STRICT) that enforces a specific schema compliance, and any deviation from this schema will result in an error. Certain properties, like default field properties, might not be supported in strict modes.

Data Type Mismatch

The error can also occur if there is a mismatch between the expected data type in the schema and the actual data type of the parameters provided in the request. For instance, if the schema expects a string but receives a boolean, it will trigger this error.
