Playwright TypeError: 'function' object does not support the asynchronous context manager protocol

Question

I use Pyrogram to troll messages from the Telegram channel. Next, I extract the necessary data, which I use Playwright to enter into a form on some site.

Here is an example of the code:

import re
import logging
from datetime import datetime
from typing import AsyncGenerator


from pyrogram import filters, Client
from pyrogram.types import Message
from playwright.async_api import async_playwright


from keys import API_ID, API_HASH, CANAL_ID_IMEX, LOGIN, PASSWORD, URL


client = Client("my_session", api_id=API_ID, api_hash=API_HASH)


async def get_codes(message: Message) -> AsyncGenerator[str, None]:
    """Example of the message text:
    'ZM_GDB4SRHQNK Activate in bonuses.'
    """
    promo = [c
             for codes in re.findall(
                 r"(^[a-zA-Z]{2}_[a-zA-Z0-9]{10})",
                 message.text, flags=re.MULTILINE
                 )
             for c in codes if c]

    for code in promo:
        yield code


@client.on_message(filters.chat(CANAL_ID_IMEX))
async def message_handler(client: Client, message: Message) -> None:
    async for code in get_codes(message):
        with async_playwright() as playwright:
            browser = await playwright.chromium.launch()
            context = await browser.new_context()
            page = await context.new_page()
            await page.goto(URL)

if __name__ == '__main__':
    client.run()

This line with async_playwright() as playwright: leads to the following error:

2024-03-08 21:16:02,915 - INFO - 256 | 2024-03-08 21:16:03 | ZM_Z263A89F4R | 0:00:00.000022

  File "/home/svbazuev/Zooma/main.py", line 99, in message_handler
    with async_playwright() as playwright:
TypeError: 'function' object does not support the context manager protocol

When I made the changes suggested by ggorlen:

@client.on_message(filters.chat(CANAL_ID_IMEX))
async def message_handler(client: Client, message: Message) -> None:
    async for code in get_codes(message):
        if code:
            async with async_playwright as p:
                browser = await p.chromium.launch()

I got this error:

2024-03-09 13:02:59,842 - INFO - 274 | 2024-03-09 13:02:59 | ZM_726HBNYRA2 | 0:00:00.000029

    async with async_playwright as p:

If I first save the necessary data and upload it separately to the form, I succeed. But I want to execute immediately without saving intermediate results.

I didn't find any explicit instructions in the documentation. I must be missing something. How to solve it?

At first, I used the synchronous implementation of Playwright (Windows OS). I think the problem is related to this. The asynchronous version of Playwright (OS Linux) is already being used in the code example. But I could be wrong...

Resume

Thanks to ggorlen's attentiveness, it became clear that there was no problem.

I was inattentive myself and missed async in this line:
with async_playwright() as playwright:
And then, looking into ggorlen's "notebook", I missed () in this line:
async with async_playwright as p:

Be careful!
