Как исправить ошибку с отправкой фото aiogram, python?

Question

[kolyart2022]

Пробую отправить фото в Telegram, используя библиотеку aiogram, но не получается, выходит ошибка.

Код:

import asyncio
from aiogram import Bot, types, Dispatcher
from aiogram.filters.command import Command
from aiogram.enums import ParseMode

import config
import keyboard

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

@dp.message(Command('start'))
async def startMessage(message: types.Message):
	await bot.send_photo(message.chat.id, open('pictures/cover.jpg', 'rb'))


async def main():
	await dp.start_polling(bot)

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

Ошибка:

Cause exception while process update id=343042211 by bot id=7197311239

как насчет сначала почитать доки https://docs.aiogram.dev/en/latest/api/methods/sen... а только потом прибегать сюда?
