[🐛 Bug]: (Python) /selenium/chromedriver/linux64/119.0.6045.105/chromedriver unexpectedly exited. Status code was: -5

[voelv]

What happened?

My solution works locally on windows 10. with python 3.12

Deployed to a linux server with Python 3.11.5 i get the exception

Service /home/project/.cache/selenium/chromedriver/linux64/119.0.6045.105/chromedriver unexpectedly exited. Status code was: -5

selenium.common.exceptions.WebDriverException: Message: Service /home/project/.cache/selenium/chromedriver/linux64/119.0.6045.105/chromedriver unexpectedly exited. Status code was: -5

How can we reproduce the issue?

Python code:


def init_browser():
    #Init browser
    logging.info("Initializing browser object")
    try:
        options = webdriver.ChromeOptions()
        options.add_argument('--headless=new')
        # block image loading
        options.experimental_options['prefs'] = {
        "profile.managed_default_content_settings.images": 2
        }
        browser = webdriver.Chrome(options=options)
    except Exception as ex:
        logging.exception(ex)
        sys.exit()
    else:
        return browser

Updated my code to try with a manually downloaded driver:

config has:

"chromedriver":{
        "local": True,
        "path":"/home/project/home/chrome/chromedriver"
    }

Python:

def init_browser():
    logging.info("Initializing browser object")
    try:
        options = webdriver.ChromeOptions()
        options.add_argument('--headless=new')
        # block image loading
        options.experimental_options['prefs'] = {
        "profile.managed_default_content_settings.images": 2
        }

        #Init browser
        if config["chromedriver"]["local"]:
            service = Service(executable_path=config["chromedriver"]["path"])
            browser = webdriver.Chrome(service=service,options=options)
        else:
            browser = webdriver.Chrome(options=options)
    except Exception as ex:
        logging.exception(ex)
        #Selenium Logger
        sel_logger.debug(ex)
        sys.exit()
    else:
        return browser

Again, this works on windows with the correct path to a manually downloaded driver.

Is your Linux server running on x64 or arm/aarch64?

[voelv]

Architecture x86_64
Kernel Version 4.18.0-477.21.1.lve.1.el8.x86_64

[titusfortner]

Hmm, yeah, I'm really not sure here. Everything looks correct from your code, to what gets downloaded, to where it is downloading, to the file permissions....

If the architecture were arm/aarch it would explain what we're seeing...

What happens if you try with Firefox?
What happens if you specify an older browser version?

[voelv]

Yeah, guess I could try that.
I'll get back to you

[voelv]

Tried with Firefox.
Worked on windows.
On Linux it just hanged for 30 minutes, and then I killed the proces....
(It hangs if I start it again)

Can... can you try it with Firefox and specify in Service class this one https://github.com/mozilla/geckodriver/releases/download/v0.33.0/geckodriver-v0.33.0-linux-aarch64.tar.gz just to completely rule it out?

[voelv]

I have a suspicion that it's related to network. I don't know what specific error codes I would get, if the network was somehow blocked?
But i'll try to change the port used and see what happens

[titusfortner]

If the network were blocked, you wouldn't be able to get the files downloaded to the .cache directory.

This is failing trying to start the driver that was downloaded, which shouldn't be doing anything with the network. It's weird that the error is the same for both arm64 and x86 drivers.

I have no idea on this one. Selenium is sending the right commands to do the right things. Maybe someone in Mailing list or on Stack Overflow has a better guess.
