[BUG] AttributeError: 'Botright' object has no attribute '_async_class_task_store'

[Zorkats]

While using botright in an automation script with playwright, I encountered the following error when trying to open a browser with botright_client.new_browser():

Traceback (most recent call last):

AttributeError: 'Botright' object has no attribute '_async_class_task_store'

Steps to Reproduce:

Install dependencies with pip install botright playwright

Run the following script:

import asyncio
from botright import Botright

async def download_pdfs():
    async with Botright(headless=True) as botright_client:
        browser = await botright_client.new_browser()
        page = await browser.new_page()
        await page.goto("https://example.com")
        print(await page.title())
        await browser.close()

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

The error occurs when attempting to launch the browser.

Expected Behavior:

The browser should open in headless mode, navigate to the provided URL, and close without any errors. Environment:

OS: Windows 10
Python Version: 3.11
Botright Version: 0.5.1
Playwright Version: 1.40.0
hcaptcha-challenger Version: 0.10.1.post2
Other Installed Packages:
    async-class: 0.5.0
    numpy: 1.26.4
    httpx: 0.27.2

Possible Cause:

It seems the issue is related to the initialization of the _async_class_task_store attribute in the Botright class. This attribute may not be properly initialized during the browser launch process. Solutions Tried:

I followed the official documentation and reinstalled all dependencies in a fresh environment, but the issue persists. Additional Comments:

This issue seems to be connected with how async_class is integrated into the flow of botright. I would appreciate any guidance on how to resolve this, or if a future update might address this behavior.

[randomsnippets]

Do it like this and it shall work:

import asyncio
from botright import Botright

async def download_pdfs():
    client = await Botright(headless=True)
    browser = await botright_client.new_browser()
    page = await browser.new_page()
    await page.goto("https://example.com")
    print(await page.title())
    await browser.close()

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