        async with self.app:
            await self.app.send_photo(
                chat_id='@filmas_tiktok',
                photo=about['img_link'],
                caption=MessagePaterns.FILM_AFISH_PATTERN(about),
                parse_mode='html',
                reply_markup=KeyBoards.get_link_kb_pyro(about['shorturl'])
                )

A keyboard button include url to site and text of button.

>Solution :

If I read this part right:

btn = pyrokbbut(text,url=url)
kb = pyrokbmk(inline_keyboard=[btn])

you’re defining one button, and pass that as a list to the keyboard itself. Pyrogram and its InlineKeyboardMarkup require a list of lists, where the outer list is the rows, the inner list the buttons of each row.

You’ll want something that looks like this:

keyboard = [  # List of rows:
    [button, button],  # First Row
    [button],  # Second Row
]
