Fix UnprocessableEntityError

✅ Solution

The OpenAI UnprocessableEntityError (422) often arises when the input to an OpenAI function, particularly with tool calls, doesn't conform to the schema defined in the function's specification. To fix this, carefully validate that the arguments passed to your function calls match the expected data types, required fields, and allowed values outlined in the function's description, paying close attention to nested structures and enums. Specifically, ensure the tool_choice parameter is correctly set.
