How to send a bitmap through a telegram bot?

Question

Python

I get a picture from my database if I output it to text like this memory at 0x0000029C34993640 (a picture in bytea format) but when I write await bot.send_photo(message.chat.id, elem[8])(elem[8] is my picture just)
gives me an error - aiogram.utils.exceptions.BadRequest: Image_process_failed
(what could be wrong?)
