TypeError：MessageFilter.check_update() 缺少 1 个必需的位置参数：'update' | python-telegram-bot 中的 ConversationHandler

Question

我开始学习 Python，并想知道是否有可能以某种方式在 python-telegram-bot 上制作“FSM”。我认为这是一个愚蠢的问题，但是......

我想将电报机器人放在谷歌云功能第一代上，所以我使用此代码使机器人工作

main.py：

    import asyncio
    import os
    import re


    from functions_framework import http
    from telegram.ext import (
     Application,
     CommandHandler,
     MessageHandler,
     filters,
     CallbackQueryHandler,
     ConversationHandler,
    )
    from telegram import Update

    from handlers.handlers import start
    from text_const import CANCEL
    from handlers.fsm import *


    @http
    def telegram_bot(request):
     return asyncio.run(main(request))


    async def main(request):
     token = '...'
     app = Application.builder().token(token).build()
     bot = app.bot

     app.add_handler(CommandHandler("start", start))   
     app.add_handler(conv_handler)
     app.add_handler(MessageHandler(filters.Regex(f"^{CANCEL}$"), 
      cancel_deal))
    
    if request.method == 'GET':
        await 
         bot.set_webhook(f'https://{request.host}/telegram_bot')
        return "set"

    async with app:
        update = Update.de_json(request.json, bot)
        await app.process_update(update)

    return "ok"

正如我之前所说，我刚刚开始学习Python。在创建对话脚本“aiogram 中的 FSM”时，我惊呆了。我将所有脚本逻辑移至单独的 fsm.py 文件中

fsm.py：

from telegram import Update, InlineKeyboardMarkup
from telegram.ext import (
 Application,
 MessageHandler,
 filters,
 CallbackQueryHandler,
 ConversationHandler,
 ContextTypes,
)
from text_const import *


async def request(update: Update, context: ContextTypes.DEFAULT_TYPE):
 await update.message.reply_text('Hi, U good?')
 return 1

async def first_response(update: Update, context: ContextTypes.DEFAULT_TYPE):
 answer = update.message.text
 if answer.lower() in ['yeap', 'yes']:
    await update.message.reply_text('U male?')
    return 2
 else:
    await update.message.reply_text('Bye...')
    return ConversationHandler.END

async def second_response(update: Update, context: ContextTypes.DEFAULT_TYPE):
 sex = {'Male': 'U male', 'Female': 'U female'}
 user_answer = update.message.text
 answer_sex = sex.get(user_answer, 'not found')
 await update.message.reply_text('TY:')
 await update.message.reply_text(answer_sex)
 return ConversationHandler.END

async def cancel_deal(update: Update, context: ContextTypes.DEFAULT_TYPE):
 await update.message.reply_text("Bye! Good day!")
 return ConversationHandler.END


conv_handler = ConversationHandler(
  entry_points= [MessageHandler(filters.Regex(f"^{REQUEST}$" 
), request)],
 states={
    1: [MessageHandler(filters.Text, first_response)],
    2: [MessageHandler(filters.Text, second_response)]
    },
 fallbacks=[MessageHandler(filters.Regex(f"^{CANCEL}$"), 
  cancel_deal)]    
)

之后，我们向机器人发送了一个负责触发对话脚本的短语，但是当我尝试输入任何消息时，我在日志中收到错误：

Traceback (most recent call last):   File "/layers/google.python.pip/pip/lib/python3.12/site-packages/telegram/ext/_application.py", line 1254, in process_update     check = handler.check_update(update)  # Should the handler handle this update?

         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

告诉我为什么会发生这种情况，也许你可以指出代码中的缺陷或弱点，我将不胜感激！

困倦时学习代码不是一个好主意。错误是我错误地写了“过滤器模块”。 曾是： 过滤器.文本 并要求： 过滤器.TEXT

conv_handler = ConversationHandler(
 entry_points= [MessageHandler(filters.Regex(f"^{REQUEST}$"), request)],
  states={
   1: [MessageHandler(filters.TEXT, first_response)],
   2: [MessageHandler(filters.TEXT, second_response)]
  },
  fallbacks=[MessageHandler(filters.Regex(f"^{CANCEL}$"), cancel_deal)]    
)
