I do not understand what is wrong | Vk.api timeout=self.wait + 10 | What's wrong?

Question

Python

I'm trying to write the most common bot on vk.api without any functionality, the python gives me a funny error

Traceback (most recent call last):
  File "F:\Bruh\Site\Bruh\BotMGL.py", line 23, in <module>
    for event in longpoll.listen():
  File "C:\Users\Admin\AppData\Local\Programs\Python\Python39\lib\site-packages\vk_api\longpoll.py", line 619, in listen
    for event in self.check():
  File "C:\Users\Admin\AppData\Local\Programs\Python\Python39\lib\site-packages\vk_api\longpoll.py", line 558, in check
    timeout=self.wait + 10
TypeError: can only concatenate str (not "int") to str

Sopstna the code itself, I can not understand at all what the problem is.
Although I don’t think at all that this is somehow related to the code, because a couple of days ago everything was fine, but now the problem just appeared out of nowhere.

import vk_api
from vk_api.longpoll import VkLongPoll, VkEventType
from vk_api.keyboard import VkKeyboard
from vk_api.keyboard import VkKeyboardColor

token = 'не скажу'
vk_session = vk_api.VkApi(token=token)
longpoll = VkLongPoll(vk_session,'и это тоже')
vk = vk_session.get_api()
keyboard = VkKeyboard()

for event in longpoll.listen():
    if event.type == VkEventType.MESSAGE_NEW and event.to_me and event.text:
      if event.text == 'Начать':
          keyboard.add_button(label="Кнопка 1",color=VkKeyboardColor.POSITIVE)
          keyboard.add_line()
          keyboard.add_button(label="Кнопка 2", color=VkKeyboardColor.PRIMARY)
          keyboard.add_button(label="Кнопка 3", color=VkKeyboardColor.SECONDARY)
          vk.messages.send(
              user_id=event.obj.from_id,
              random_id=event.random_id,
              message='Выберите то, что вы хотите сделать',
              keyboard=keyboard.get_keyboard())

UPD: Most likely, the matter is in the code itself and you just need to optimize the code, as I understand it.
I'm sure I'm not the only one so "very smart" and the question, as it were, will always be relevant

Answer 1

The problem is "this too" longpoll = VkLongPoll(vk_session,'и это тоже'). There should be a delay time of type int, but what you have there is not clear
