I m 在Aiogram上写了一把机器人。 我根据文件做了一切,但我有了一个错误。 我第一次看到她。 请帮助我解决问题

def on_startup(bot: Bot) -> None:
    asyncio.create_task(start_schedule(bot))


async def start_schedule(botself):
    aioschedule.every().day.at( 00:00 ).do(lottery.lottery_finish, botself)
    while True:
        await aioschedule.run_pending()
        await asyncio.sleep(1)


async def main():
    bot = Bot(token=BOT_TOKEN, parse_mode= html )
    dp = Dispatcher()

    dp.startup.register(on_startup)

    dp.include_routers(main_menu.router, order.router, report.router, phone.router, location.router, receipt_scan.router, admin_panel.router, lottery_panel.router, products_panel.router, post_panel.router, markets_panel.router, early_close_panel.router, code.router, pre_admin_panel.router, availability_panel.router)
    await bot.delete_webhook(drop_pending_updates=True)
    await dp.start_polling(bot)


if __name__ ==  __main__ :
    logging.basicConfig(level=logging.INFO, stream=sys.stdout)
    asyncio.run(main())
