很多tg机器人，运行一段时间后出现消息问题。

如果机器人是基于telepot开发的，可能错误是这样的：

Faced with the same problem:

Traceback (most recent call last):
  File "C:\Program Files\Python37\lib\site-packages\telepot\aio\loop.py", line 38, in run_forever
    self._update_handler(update)
  File "C:\Program Files\Python37\lib\site-packages\telepot\aio\loop.py", line 82, in <lambda>
    self._handle(_extract_message(update)[1]))
  File "C:\Program Files\Python37\lib\site-packages\telepot\loop.py", line 111, in _extract_message
    'pre_checkout_query'])
  File "C:\Program Files\Python37\lib\site-packages\telepot\__init__.py", line 68, in _find_first_key
    raise KeyError('No suggested keys %s in %s' % (str(keys), str(d))
)

Environment:

Python 3.7.7

telepot==12.7

Attempts:

Using @Carlog suggestion raised for me the exception:

Traceback (most recent call last):
  File "C:\Program Files\Python37\lib\site-packages\telepot\aio\loop.py", line 38, in run_forever
    self._update_handler(update)

    self._handle(_extract_message(update)[1]))
  File "C:\Program Files\Python37\lib\site-packages\telepot\aio\__init__.py", line 912, in handle
    id = calculate_seed(msg)
  File "C:\Program Files\Python37\lib\site-packages\telepot\delegate.py", line 303, in f
    seed = fn(msg)
  File "C:\Program Files\Python37\lib\site-packages\telepot\delegate.py", line 9, in w
    return fn(*args, **kwargs)
  File "C:\Program Files\Python37\lib\site-packages\telepot\delegate.py", line 24, in <lambda>
    if types == 'all' or msg['chat']['type'] in types
TypeError: 'int' object is not subscriptable

这是因为telepot库已经不更新了，有时候tg官方的更新，会导致一些消息接收失败。

这里有个解决方案可以尝试：

找到文件 Lib\site-packages\telepot\loop.py 修改这个函数 _extract_message. （修改前最好备份）

def _extract_message(update):

    key = _find_first_key(update, ['update_id',
                                   'message',
                                   'edited_message',
                                   'channel_post',
                                   'edited_channel_post',
                                   'callback_query',
                                   'inline_query',
                                   'chosen_inline_result',
                                   'shipping_query',
                                   'pre_checkout_query'])

    if key != 'update_id':
        return key, update[key]

    if 'message' in update.keys():
        return 'message', update['message']

    if 'my_chat_member' in update.keys():
        return 'message', {'message_id': update['update_id'], 
                            'from': update['my_chat_member']['from'], 
                            'chat': update['my_chat_member']['chat'], 
                            'date': update['my_chat_member']['date'], 
                            'text': f"It's update_id {update['update_id']}"
                        }
    raise Exception('The hotfix for update_id bug needs to upgrade')
