大家好！我正在使用 pyTelegramBotApi 编写 Telegram 机器人。那是我的代码：
import telebot
from telebot import apihelper
bot = telebot.TeleBot(TOKEN);
apihelper.proxy = {'https': 'socks5://154.221.21.197:10800'}
bot.polling()
当我尝试运行它时，出现错误：
2019-11-28 00:44:10,836 (util.py:66 PollingThread) ERROR - TeleBot: "AttributeError occurred, args=("'NoneType' object has no attribute 'format'",)

它是什么，我该如何解决这个问题？代理正在工作（试图与应用程序连接），gunicorn，PySocks，pyTelegramBotAPI，请求，urllib3 最新版本已安装。
- IDE：PyCharm 3.0.3
- Python 3.7.4
谢谢！
