Python，await："await state.finish()“出错

Question

我正在做一个电报机器人，用的是API API。我是它的初学者，所以我对"await state.finish()“行有一个问题。当我启动我的python文件时，我得到了这个错误：

C:\Users\User\AppData\Local\Programs\Python\Python38\lib\site-packages\aiogram\dispatcher\dispatcher.py:409>：<任务完成名称=‘任务-23’coro= "C:\Users\User\AppData\Local\Programs\Python\Python38\lib\site-packages\aiogram\dispatcher\dispatcher.py"，(1055580872)>回溯(最近一次调用)：文件coro=

我的代码如下：

import logging
from aiogram import Bot, Dispatcher, executor, types
from aiogram.contrib.fsm_storage.memory import MemoryStorage
from aiogram.dispatcher.filters.state import State, StatesGroup
from aiogram.dispatcher import FSMContext
import random

TOKEN = 'HERE IS TOKEN'

#
logging.basicConfig(level=logging.INFO)

storage = MemoryStorage()
bot = Bot(token=TOKEN)
dp = Dispatcher(bot, storage=storage)

class UsersClass(StatesGroup):
    users = State()

@dp.message_handler(commands=['start', 'help'])
async def send_welcome(message: types.Message):
    await message.reply("Hi!\nI'm Bot!!!!")

@dp.message_handler(commands=['random'])
async def random_cmd(message: types.Message):
    # old style:
    # await bot.send_message(message.chat.id, message.text)
    # await message.answer(random.choice())
    await UsersClass.users.set()
    await message.reply("Write the names of all participants separated by a space")

@dp.message_handler(state=UsersClass.users)
async def get_random_user(message: types.Message, state: FSMContext):
    async with state.proxy() as data:
        data['users'] = message.text.split(' ')
        await bot.send_message(message.chat.id, f"Chosed: {random.choice(data['users'])}")
        await state.finish()

if __name__ == '__main__':
    executor.start_polling(dp, skip_updates=True)

如果可以的话，请帮忙

好吧，我找到答案了。问题在_cleanup中的文件"C:\Users\User\AppData\Local\Programs\Python\Python38\lib\site-packages\aiogram\contrib\fsm_storage\memory.py"，第108行。self.data没有任何钥匙。我通过向_cleanup函数添加一些新的行解决了这个问题，如下所示：

def _cleanup(self, chat, user):
        if chat not in self.data.keys() or user not in self.data[chat].keys():
            return
        if self.data[chat][user] == {'state': None, 'data': {}, 'bucket': {}}:
            del self.data[chat][user]
        if not self.data[chat]:
            del self.data[chat]

现在我没有任何错误了！
