When writing a code for a telegram bot, an error pops up. What to do?

Question

Python

The code:

import config
import logging

from aiogram import Bot, Dispatcher, executor, types

logging.basicCongig(level=logging.INFO)

bot = Bot(token=config.TOKEN)
dp = Dispatcher(bot)

@dp.message_handler()
async def echo(message: types.Message):
  await message.answer(message.text)


if __name__ == "__main__":
  executor.start_polling(dp, skip_updates=True)

Mistake:

async def echo(message: types.Message):
        ^
SyntaxError: invalid syntax<
