Chromium browser issue with chromedriver

[MortazaG]

Hi!
I uninstalled Chrome today and installed an older version of Chromium browser instead, version 109.
I've downloaded the proper chromedriver and at first I got this error:

TypeError: expected str, bytes or os.PathLike object, not NoneType

Which was fixed by adding:
options.binary_location = 'C:/Users/username/AppData/Local/Chromium/Application/chrome.exe'

Although, using regular Selenium there was no need for setting this path.

After setting the path to the binary file, I now get this error message:

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot connect to chrome at 127.0.0.1:56118
from session not created:
This version of ChromeDriver only supports Chrome version 110
Current browser version is 109.0.5414.0

I have double and triple checked that I have downloaded the right version of the chromedriver.

I have set its path through:
path = 'D:/path/to/chromedriver.exe'
driver = uc.Chrome(options=options, executable_path=path)

But I am still getting the above error message.

Is there a specific way of setting up undetected_chromedriver to work properly with the Chromium browser?

Found a solution for the problem.
forget about all the extra arguments and updates/ etc.

If you are using the DIR folder that currently has a browser profile open. it will not work. you have to close everything first and then run it. That was the workaround for it for me.

Thanks for the reply! I tried what you said, but i still get the same error:

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot connect to chrome at 127.0.0.1:49812 from session not created:
This version of ChromeDriver only supports Chrome version 110
Current browser version is 109.0.5414.0

Do you know why setting the executable_path to the chromedriver isn't working? Or what kind of special tweaking is necessary for chromium browsers as mentioned in the readme file?

Works also on Brave Browser and many other Chromium based browsers, some tweaking

not sure if @MortazaG has already found the solution, but you can simply do this:

   import undetected_chromedriver as uc
   driver = uc.Chrome( version_main = 110 )
