Unable to call function using python-telegram-bot in ConversationHandler

[astrid-net]

Hello everyone, In my code when the bot is triggered the function user_exist() is triggered. If returns False, the function new_account() is triggered and works perfectly, instead, when returns True, it should trigger the function wallet_handler(), but it can't. The code is running in a Conversation Handler. I thought I did everything fine, but I can't figure out why the function wallet_handler() is not triggered. Anyone can help me? This is my code:

import logging
import data
from web3 import Web3
from telegram import ReplyKeyboardMarkup, ReplyKeyboardRemove, Update
from telegram import InlineKeyboardButton, InlineKeyboardMarkup, ReplyKeyboardMarkup
from telegram.ext import (
    Updater,
    CommandHandler,
    MessageHandler,
    Filters,
    ConversationHandler,
    CallbackContext,
    CallbackQueryHandler,
)

NEW_ACCOUNT, WALLET_HANDLER= range(2)

def start(update: Update, context: CallbackContext) -> int:
    chatid = update.message.chat_id

    if data.user_exist(chatid) == True:
        print('s')
        return WALLET_HANDLER
    if data.user_exist(chatid) == False:
        update.message.reply_text('This is your first time with us! Please insert a wallet')  
        return NEW_ACCOUNT


def new_account(update: Update, context: CallbackContext) -> int:
    chatid = update.message.chat_id
    wallet = update.message.text

    if Web3.isAddress(wallet) == True:
        data.new_account(chatid, wallet)
        update.message.reply_text('New account succesfully created.\nWelcome to Tarsier. Enjoy it!')
        return WALLET_HANDLER
    else:
        update.message.reply_text('Wallet Address invalid.\nPlease insert a valid Wallet Address.')
        return NEW_ACCOUNT
    

def wallet_handler(update: Update, context: CallbackContext) -> int:
    update.message.reply_text('aaa')
    return ConversationHandler.END

def cancel(update: Update, context: CallbackContext) -> int:
    """Cancels and ends the conversation."""
    user = update.message.from_user
    update.message.reply_text(
        'Bye! I hope we can talk again some day.', reply_markup=ReplyKeyboardRemove()
    )

    return ConversationHandler.END


def main() -> None:
    """Run the bot."""
    # Create the Updater and pass it your bot's token.
    updater = Updater("TOKEN")

    # Get the dispatcher to register handlers
    dispatcher = updater.dispatcher

    # Add conversation handler with the states GENDER, PHOTO, LOCATION and BIO
    conv_handler = ConversationHandler(
        entry_points=[CommandHandler('start', start)],
        states={
            NEW_ACCOUNT: [MessageHandler(Filters.text & ~Filters.command, new_account)],
            WALLET_HANDLER: [MessageHandler(Filters.text & ~Filters.command, wallet_handler)],
        },
        fallbacks=[CommandHandler('cancel', cancel)],
    )

    dispatcher.add_handler(conv_handler)
    updater.start_polling()
    updater.idle()


if __name__ == '__main__':
    main()

Can you reduce the example such that it doesn't relay on web3 so that one can try to run it?

@Bibo-Joshi i have updated. Even if what interests me is when return WALLET_HANDLER. thank you.

I ran the example with the following modification:

def start(update: Update, context: CallbackContext) -> int:
    if context.args:
        print('s')
        return WALLET_HANDLER
    else:
        update.message.reply_text('This is your first time with us! Please insert a wallet')
        return NEW_ACCOUNT

(input doesn't work - use /start some text to get into the if-clause)

I don't see an issue. If you type /start foo and then some arbitrary text, the bot replies with works correctly.

I ran exactly the example like yours, but the issue is not fixed. It doesn't answer works correctly. I don't know what to do.

@Bibo-Joshi tried also on different operative-system with libraries updated. issue still not fixed...

note that after sending /start foo, the bot does not reply anything (it just runs print('s'). but if you then enter some text anyway, it replies works correctly, as expected.
