Why does event.object.text return None?

Question

Python

This problem arose when a message is sent in a conversation "bot" sees that it has arrived, but says
that the message text is empty, that is, it returns None. Point out the mistake please

import requests
from vk_api.bot_longpoll import VkBotLongPoll, VkBotEventType
from vk_api.utils import get_random_id

vk_session = vk_api.VkApi(token = 'my_token')

longpoll = VkBotLongPoll(vk_session, '189470911')
vk = vk_session.get_api()

variants = ["привет", "Привет"]

while True:
  for event in longpoll.listen():
    if event.type == VkBotEventType.MESSAGE_NEW and event.from_chat:
      print(event.object.text)
# выводит: None

Answer 1

Event.message.text?
VK here somehow updated the api and the old methods of messages basically no longer work. Check out the documentation and new features of messages
