How to save geodata and photos in the MySQL database using the Pytelegrambotapi library (does not give errors, saves the first 2 parameters) but there is no geo and photo?

    bot.register_next_step_handler(msg, process_photo_step)

def process_photo_step(message):
    user_id = message.from_user.id

    val = (user_id, user.openvisit, user.geo, user.photo)
    cursor.execute(sql, val)
    db.commit()

    msg = bot.send_message(message.chat.id, "Спасибо")

bot.enable_save_next_step_handlers(delay=2)

bot.load_next_step_handlers()

if __name__ == '__main__':
    bot.polling(none_stop=True)
