USER DATA DIR CRASH

[MakDon]

I am facing a problem similar with #1567
My Chrome version:

Google Chrome | 118.0.5993.117 (Official Build) (arm64)

my code:

user_data_path = "my user data dir"
self.driver = uc.Chrome(user_data_dir=user_data_path, debug=True)
self.driver.get(url)

When I run the code, what happens is:

• The Chrome has successfully been run with Command Line, without opening the target url:

/Applications/Google Chrome.app/Contents/MacOS/Google Chrome --user-data-dir=<my user data dir> --remote-debugging-host=127.0.0.1 --remote-debugging-port=54805 --lang=en-US --no-default-browser-check --no-first-run --no-sandbox --test-type --window-size=1920,1080 --start-maximized --no-sandbox --log-level=0 --flag-switches-begin --flag-switches-end

• the Python code crashes after timeout, throwing Message: unknown error: cannot connect to chrome at 127.0.0.1:60256 Exception

What I found is that the debug port from chrome://version/ is different from the port of the Exception message:

• --remote-debugging-port=54805
• cannot connect to chrome at 127.0.0.1:60256

Is it the reason why the code crashes?

It seems that the remote debugging port is saved into user_data_dir files so it would use the same port in every boot, but the undetected-chromedriver would use a random free port instead, which causes this issue.

My workaround is, explictly explicitly set the port using:
self.driver = uc.Chrome(user_data_dir=user_data_path, debug=True, port=54805)

And it works as far as I could see.
