Basic TelegramBot initialization fails

[matthewaturner]

Perfectly willing to accept that I have done something wrong here, but following the example from the telegram.py source code I have the following:

import pandas as pd
import vectorbt as vbt
import ccxt
import logging
from telegram.ext import CommandHandler
from .. import configuration as global_config

logging.basicConfig(level=logging.INFO)

class MyTelegramBot(vbt.TelegramBot):
    @property
    def custom_handlers(self):
        return (CommandHandler('get', self.get),)
    
    @property
    def help_message(self):
        return "Type /get [symbol] [exchange id (optional)] to get the latest price."
    
    def get(self, update, context):
        chat_id = update.effective_chat.id
    
        if len(context.args) == 1:
            symbol = context.args[0]
            exchange = 'binance'
        elif len(context.args) == 2:
            symbol = context.args[0]
            exchange = context.args[1]
        else:
            self.send_message(chat_id, "This command requires symbol and optionally exchange id.")
            return
        try:
            ticker = getattr(ccxt, exchange)().fetchTicker(symbol)
        except Exception as e:
            self.send_message(chat_id, str(e))
            return
        self.send_message(chat_id, str(ticker['last']))


if __name__ == '__main__':
    print(global_config.settings['telegram']['token'])
    vbt.settings['messaging']['telegram']['token'] = global_config.settings['telegram']['token']
    telegram_bot = MyTelegramBot(token=global_config.settings['telegram']['token'])

This fails with the following output:

(pytrade37) PS C:\Users\~\source\repos\pytrade> python -m pytrade.telegram_bot.bot

    raise ValueError('`token` or `bot` must be passed')
ValueError: `token` or `bot` must be passed

Any help appreciated. I'm not used to python (C# for my day job). I can follow the stack trace roughly but with all the loose typing and generic argument lists being passed I can't quite follow what is going on here.

Hi @matthewaturner, I can reproduce the issue with the latest python-telegram-bot version. The fix will come out with 0.22.0. In the meantime, please use python-telegram-bot==13.4.1.
