Huge bug in undetected-chromedriver v2 #384

Avnsx · 2021-12-05T00:19:56Z

it's unironically so big that I can't even load up undetected chromedriver v2 with the basic code from your ReadMe

import undetected_chromedriver.v2 as uc
driver = uc.Chrome()
driver.get('https://nowsecure.nl')

ouput:

        This probably means that you are not using fork to start your

AttributeError: 'Chrome' object has no attribute 'service'

I did find a solution and that is just writing it into main:

if __name__ == '__main__':
    import undetected_chromedriver.v2 as uc
    driver = uc.Chrome()
    driver.get('https://nowsecure.nl')

but this is unacceptable and it is restricting me in freely formatting my code, also forcing me to use an entry point.
I'm encountering this bug in latest version of uc v2 and python 3.8.10 for windows 10
Please fix this as soon as possible @ultrafunkamsterdam 🙏🏼

crane-denny · 2021-12-05T11:26:31Z

@ultrafunkamsterdam
For some reasons I don't understand yet you are spawning a second instance of Chrome. At least I assume this because of a new user-data-dir. And the moment this happens it breaks.

I am now not sure what to do next. It could be that this lib is really not selenium 4 ready like you said in the readme. But then I would expect it to be set in setup.py to avoid conflicts.
I will leave this up to your hands since you know your code better then me. :)

wildangunawan · 2021-12-11T12:18:19Z

Downgrade to 3.0.3 as in this issue suggestion.

Also don't use Python 3.10 if you don't want to face another undetected-chromedriver bug

koljaoh · 2021-12-15T18:38:33Z

Hope this gets a real fix soon (there are reasons why I can't use 3.0.3 and the if name == 'main': doesnt work in all cases)

ultrafunkamsterdam · 2021-12-22T13:26:42Z

all fixed

Charcadet · 2021-12-23T13:58:08Z

all fixed

I'm still having the same issue.
UC 3.1.1
Python 3.7.8

import undetected_chromedriver as uc
driver = uc.Chrome()
driver.get('https://nowsecure.nl')

Gives me:

I am having exactly the same error, I'm on a fresh install of python 3.10 and undetected-chromedriver 3.0.3. @ultrafunkamsterdam could you please explain what the correct version is? I've been trying every answer in all these threads on this issue and it is not solving it.

1 - A script called test.py is not a great idea.
2 - In fact this makes perfect sense.
Your program is simply exiting before chrome is fully spawned. if your program exits, chromedriver exits.. never been different except for the error, which is justifyable since some multiprocess black magic makes sure Chrome has no parent process.

It seems to me that what you're really looking for is a interactive session.
in that case, use ipython.

That all being said. I was able to reproduce, although it being an edge case, I have a "fix" for this, but i need to test it first. will commit later.

Even when running my main project I'm trying to use this with, which doesn't insta exit and is pretty long it doesn't run at all and throws the same error. Works fine with just selenium.

Temporary Solution :
Install Python 3.7.9
Install 3.0.3(pip install -Iv undetected-chromedriver==3.0.3)
Use the code
import undetected_chromedriver.v2 as uc
driver = uc.Chrome(executable_path=r'drivers/chromedriver.exe', options=options, version_main=97)

Avnsx · 2022-01-26T10:54:34Z

Nah he actually fixed it in newest version, you just have to write uc.Chrome(use_subprocess=True)

not an issue with UC, but with your threading code
