THEN Add a condition in to_sampling_params() to set structured_outputs to None when response_format.type == 'text', preventing the creation of invalid structured output parameters.

if response_format is not None:
    if response_format.type == "json_object":
        self.structured_outputs.json_object = True
    elif response_format.type == "json_schema":
        self.structured_outputs.json = json_schema.json_schema
    elif response_format.type == "structural_tag":
        self.structured_outputs.structural_tag = s_tag_obj
    elif response_format.type == "text":
        self.structured_outputs = None
