When starting the bot, it gives an error AttributeError: 'NoneType' object has no attribute 'create_task' how to fix?

Question

Python

here is the code main.py

button = KeyboardButton('➕ Add Channels')
button1 = KeyboardButton('Home')
keyboard = ReplyKeyboardMarkup(resize_keyboard=True)
keyboard.add(button)
keyboard.add(button1)
await bot.send_message(m.chat .id, text,reply_markup=keyboard, parse_mode="HTML")
else:
await bot.send_message(m.chat.id, " ❌ You are not allowed to use this bot. ", parse_mode="HTML")

@dp.message_handler()

if __name__ == '__main__':
dp.loop.create_task(get_channels())

Error:

Answer 1

dp.loop.create_task(get_channels())
At this point, the call to the dispatcher has not yet started, so there is no work cycle (loop) for it. I guess create_task() should be called inside some event handler so you can be sure the work loop is already running.
If the aiogram API has an event that fires when connected to the network, that event handler would be the appropriate place.
