deepseek does not support function calling.....

Yesterday was okay, but when I woke up, I got an error today: openai.BadRequestError: Error code: 400 - {'error': {'code': 'InvalidParameter', 'message': 'The parameter `` specified in the request are not valid: the requested model does not support function calling, please switch to a different model or contact with administrator if you believe this model should support function calling.

This is an error with your model provider. We can't do anything about whether it supports function calling or not.
