Ошибка при запуске бота unsupported callable

Делал оплату по видео ХаудиХо, всё написал, но выдает ошибку unsupportde callable. Код в котором ошибка:

@router.message(ContentType.SUCCESSFUL_PAYMENT)
async def succ_pay(msg: Message):
    paymentinfo = msg.successful_payment.provider_payment_charge_id # Здесь должно быть .to_python() но я не знаю как это выглядит в aoigram3.3.0
    for k, v in paymentinfo:
        print(f'{k} = {v}')
    await bot.send_message(msg.chat.id, f'Платеж на сумму {msg.successful_payment.total_amount // 100} {msg.successful_payment.currency} прошёл успешно!')
    #DB.status_up(msg.from_user.id, 8)
    #await rang_up(msg)

Ошибка:

    raise TypeError('{!r} is not a callable object'.format(obj))
TypeError: <ContentType.SUCCESSFUL_PAYMENT: 'successful_payment'> is not a callable object

The above exception was the direct cause of the following exception:
