[Bug]: Error: net::ERR_PROXY_CONNECTION_FAILED .... is of type playwright._impl._errors.Error

[epicwhale]

Version

1.43.0

Steps to reproduce

Example steps (replace with your own):

1. Create a new_page using a proxy_config server url that will fail:

page = await browser.new_page(
        proxy={},  # configure with a failing server
    )
await page.goto(...)

Expected behavior

Raise an exception type that can be handled in an except block similar to TimeoutError

Actual behavior

Raises a generic exception of type:
playwright._impl._errors.Error
Error('net::ERR_PROXY_CONNECTION_FAILED at http://...')

Additional context

The Error type raised and the object format would require me to string match for "net::ERR_PROXY_CONNECTION_FAILED" in the message string.

Is there a more elegant way to do this? Maybe I am missing something but could not find anything on Google or Github about this.

Environment

Browsers have individual error messages, creating different kind of error classes is outside of the scope for Playwright. (we'd need to create hundreds for each browser)

We recommend matching them via a str as you proposed as a workaround.
