ValueError: At least one bot instance is required to start polling

когда пытаюсь запустить код:

from aiogram import Bot, Dispatcher, types
import asyncio
import requests

PROBIVAPI_KEY = "YOUR_PROBIVAPI_KEY_HERE"

bot = Bot(token="7161414575:AA***4oG_gpEDzcHA1aT0fZQ")
dp = Dispatcher()

print("!BOT STARTED!")

async def get_start(message: types.Message):
    await message.answer("Hi")

async def send_welcome(message: types.Message):
    """
    This handler will be called when user sends `/start` command
    """
    await get_start(message)

async def send_help(message: types.Message):
    """
    This handler will be called when user sends `/help` command
    """
    await message.reply("Probiv Bot Template by DimonDev: @dimondevchat")

async def text(message: types.Message):
    nomer = message.text
    print(nomer)

    url = "https://probivapi.com/api/phone/info/" + nomer

    head = {
        "X-Auth": PROBIVAPI_KEY
    }

    response = requests.get(url, headers=head)
    print(response.text)

    try:
        json_response = response.json()
    except Exception:
        json_response = {}

    try:
        truecaller_api_name = str(json_response['truecaller']['data'][0]['name'])
    except Exception:
        truecaller_api_name = 'Not found'
    try:
        numbuster_api_name = str(json_response['numbuster']['averageProfile']['firstName']) + \
                             str(json_response['numbuster']['averageProfile']['lastName'])
    except Exception:
        numbuster_api_name = 'Not found'
    try:
        eyecon_api_name = str(json_response['eyecon'])
    except Exception:
        eyecon_api_name = 'Not found'
    try:
        viewcaller_name_list = []
        for tag in json_response['viewcaller']:
            viewcaller_name_list.append(tag['name'])
        viewcaller_api_name = ', '.join(viewcaller_name_list)
    except Exception:
        viewcaller_api_name = 'Not found'

    await message.reply(
        f"? База: (Numbuster): {numbuster_api_name}\n"
        f"? База: (EyeCon): {eyecon_api_name}\n"
        f"? База: (ViewCaller): {viewcaller_api_name}\n"
        f"? База: (TrueCaller): {truecaller_api_name}"
    )

async def main():
    await dp.start_polling()
    await bot.close()
    dp.register_message_handler(get_start())
    dp.register_message_handler(send_welcome())
    dp.register_message_handler(send_help())

if __name__ == '__main__':
    asyncio.run(main())

получаю ошибку:
