Why does bot reply to messages, that where sent while he was inactive

[AkiraRy]

this is snippet from my project

def start_bot():
    global loop, chat_queue, app
    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop)
    print('starting bot')
    chat_queue= []
    defaults = Defaults(parse_mode=ParseMode.HTML, tzinfo=pytz.timezone(COUNTRY))
    app = (
        Application.builder()
        .token(TOKEN)
        .defaults(defaults)
        .build()
    )

    filter_users = TypeHandler(Update, whitelist_user)
    app.add_handler(filter_users, -1)

    # Commands
    app.add_handler(CommandHandler('start', start_command))
    app.add_handler(CommandHandler('help', help_command))
    app.add_handler(CommandHandler('custom', custom_command))
    app.add_handler(CommandHandler('sticker', send_sticker))

    # Messages
    app.add_handler(MessageHandler(filters.TEXT, handle_message))
    app.add_handler(MessageHandler(filters.VOICE, handle_voice))

    # Error
    app.add_error_handler(error)
    user_states = {}
    app.context_types.context.user_states = user_states

    # chat_queue_thread = threading.Thread(target=process_chat_queue)
    # chat_queue_thread.start()
    print('pooling')

    try:
        loop.run_until_complete(app.run_polling())
    except RuntimeError as e:
        if str(e) == 'Event loop is closed':
            print('Bot stopped gracefully')
        else:
            raise
    if loop is not None:
        loop.close()




# def start_bot_in_thread():

# Flag to indicate whether the bot should stop

# Stop the bot gracefully
def stop_bot():
    global bot_thread, app
    global loop
    if loop is not None:
        loop.stop()

        loop = None



def gui():
    def start_bot_with_delay():
        global chat_queue
        chat_queue = []  # Clear the chat queue
        bot_thread = threading.Thread(target=start_bot)
        bot_thread.start()
        time.sleep(1)
        print('\n\nafter')

    customtkinter.set_appearance_mode("System")  # Modes: system (default), light, dark
    customtkinter.set_default_color_theme("blue")  # Themes: blue (default), dark-blue, green



    app = customtkinter.CTk()
    app.geometry("400x240")


    stop_button = customtkinter.CTkButton(master=app, text="Stop", command=stop_bot)
    stop_button.place(relx=0.7, rely=0.5, anchor=customtkinter.CENTER)
    button = customtkinter.CTkButton(master=app, text="CTkButton", command=start_bot_with_delay)
    button.place(relx=0.5, rely=0.5, anchor=customtkinter.CENTER)
    app.mainloop()


if __name__ == '__main__':


    gui()

Overall i have simple gui to stop and activate the bot, when i stopped him and message something via telegram and ONLY AFTER that i activate him it will start replying to messages that were sent while he was inactive. (when user messages something to bot it adds to a queue but when startnig the bot, thread or even in the function start_bot() i make sure that this queue will be empty)

also sorry for bad formatting i used this emoji for code, but it sill kinda broke

1. run_polling/run_webhook/get_updates all have a parameter called drop_pendinge_updates
2. Application.run_polling is not a coroutine function, passing it to run_until_complete makes no sense.

If i want to create gui that can operate after starting bot i need to start the telegram application in thread, and because of that i need to use asyncio. if i would just simply use button that start polling it will freeze the app. Thanks for your answer

I can`t replicate the error i was having by not running as a coroutine, but wheni tried using this start_bot() in thread it was just an error something like app.run_polling() was never awaited, even though the function start_bot() was not with async keyword. Good news is that now everything works
