Azure GPT3.5-16k 的 function calling 在下面这个请求时一定会报错

下面这段代码在请求 Azure OpenAI GPT 接口时，一定会报错：

def calculator(num1, num2, operator):
    if operator == '+':
        value = round(num1 + num2, 2)
    elif operator == '-':
        value = round(num1 - num2, 2)
    elif operator == '*':
        value =  round(num1 * num2, 2)
    elif operator == '/':
        value = round(num1 / num2, 2)
    elif operator == '**':
        value =  round(num1 ** num2, 2)
    elif operator == 'sqrt':
        value = round(math.sqrt(num1), 2)
    else:
        return "Invalid operator"
    return str(value)
