我正在尝试遵循以下Twilio Autopilot教程https://www.twilio.com/docs/autopilot/quickstart/python?code-sample=code-create-your-first-assistant-with-autopilot-7

我正在尝试用自动驾驶仪和我自己的account_sid和auth_token创建我的第一个助手。

# Download the helper library from 
https://www.twilio.com/docs/python/install
from twilio.rest import Client

# Your Account Sid and Auth Token from twilio.com/console
# DANGER! This is insecure. See http://twil.io/secure
account_sid = 'ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
auth_token = 'your_auth_token'
client = Client(account_sid, auth_token)

assistant = client.autopilot \
              .assistants \
              .create(
                   friendly_name='Quickstart Assistant',
                   unique_name='quickstart-assistant'
               )

print(assistant.sid) 

但是，当我尝试执行脚本时，我收到以下错误。
