To resolve the "deepseek response format error" with status code 422, ensure that the response_format parameter is structured correctly. The response_format should be a dictionary with a 'type' key. Update your configuration to use the following structure:

{
    "response_format": {"type": "json_object"}  # or {"type": "text"}
}

This conversion is necessary for proper JSON deserialization when making API requests to the DeepSeek API. Make sure your model_parameters include the response_format in this format to avoid the deserialization error ^[1].
