Python Telegram Bot not functioning as expected

I’m having trouble with my Python Telegram bot. It’s not working right. Here’s the code I’m using:

from telegram.ext import Updater, CommandHandler, CallbackContext

def greet(update: Update, context: CallbackContext):
    user_chat = update.effective_chat
    context.bot.send_message(chat_id=user_chat.id, text='Hi there!')


def main():
    bot = Updater('YOUR_BOT_TOKEN')
    bot.dispatcher.add_handler(CommandHandler('greet', greet))
    bot.start_polling()
    bot.idle()


if __name__ == '__main__':
    main()

I’m getting an error that says something about ‘CallbackContext’ not having a ‘message’ attribute. Can someone help me figure out what’s wrong? I’m new to this and not sure what to do next. Thanks!

I ran into a similar problem with my Python Telegram bot when I discovered that the error was due to a mismatch between the library version and the code. After upgrading to version 20, I had to modify my import statements and adjust my main function to use the Application class instead of the Updater. This resolved the issues with CallbackContext. In my experience, keeping the library up to date and reviewing the latest documentation carefully helps prevent these compatibility problems. If the error persists, verifying that all parts of the code are correctly adjusted can be very useful.

I encountered a similar issue while working on my Telegram bot project. The problem stemmed from using an older version of the python-telegram-bot library, which led to the CallbackContext error. Upgrading to version 20 or later resolved the issue, but it required several changes in the code. I updated my imports to use “from telegram import Update” and “from telegram.ext import Application, CommandHandler, ContextTypes”. I then rewrote the greet function as an async function that awaits the reply, and modified the main function to build and run the application using Application.builder().token(‘YOUR_BOT_TOKEN’).build() and app.run_polling(). These adjustments helped my bot run smoothly.

hey mate, looks like ur using an outdated version of python-telegram-bot. try upgrading to v20+ and change ur imports to:

from telegram import Update
from telegram.ext import Application, CommandHandler

also, update ur main() function. google ‘ptb v20 example’ for reference. good luck!
