Как исправить ошибку vkbottle TypeError: «MessageMin» is immutable and does not support item assignment?

Question

[Илья Бугаец]

Когда боту пишут сообщения, то я получаю ошибку:

ERROR:vkbottle:"MessageMin" is immutable and does not support item assignment
Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/vkbottle/dispatch/base.py", line 22, in route
    await view.handle_event(event, ctx_api, self.state_dispenser)
  File "/usr/local/lib/python3.9/site-packages/vkbottle/dispatch/views/abc/message.py", line 50, in handle_event
    message.state_peer = await state_dispenser.cast(self.get_state_key(message))
  File "pydantic/main.py", line 360, in pydantic.main.BaseModel.__setattr__
TypeError: "MessageMin" is immutable and does not support item assignment

Подскажите, как исправить?
