[🐛 Bug]: [Python] webdriver.service.process

[dornech]

Description

I was used to use webdriver.service.process.pid to killö a "surving" webdriver process. With upgrading to 4.38 due to a BiDi issue I now get an mypy error stating that webdriver.service.process has gone. I also do not find it in the sources.

Did I overlook something or is there a change ?

I mean, I see the POpen and the assignment to self.process in service.py but I wonder why mypy does not recognize it as before.

Reproducible Code

atexit.register(kill_driver_processes, browser, webdriver.service.process.pid)

Debugging Logs

MyPy error:
error: Item "None" of "Service | None" has no attribute "process"

I don't know what you are trying to access with webdriver.service.process.pid

pid is an attribute of the process instance in the Service class.

Did I overlook something or is there a change ?

It still exists and nothing has changed.

import atexit
from selenium import webdriver

driver = webdriver.Chrome()
atexit.register(print, driver.service.process.pid)
