Service unexpectedly exited. Status code was: 255

[otomay]

Hey man! Just found this project, glad to know someone is working on it :P
It already helped me in my dev-machine, working better than uc

But I cant make it work on my deployment server. It's an arm64 server, maybe something to do with it, since I need to use chromium instead of chrome.

Do you happen to know why?

before, with uc, I started this way:

    chrome_type = ChromeType.CHROMIUM

self.wait = WebDriverWait(self.driver, 30)

(I read about version_main in another issue, but the error I'm facing is different)

in my dev machine I was only using self.driver = Chrome(options=chrome_options) and it was fine
I also tried all variations of it, like removing the driver_executable_path and/or service, but no luck (although almost all variations worked on my dev machine)

My options are pretty simple tbh:

chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--lang=en')
chrome_options.add_argument('--log-level=3')
chrome_options.add_argument('--disable-extensions')

chrome_options.add_argument('--no-first-run')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--user-agent=%s' % ua.chrome)

just to make clear: runs ok on my arch x64-based
doesn't run on docker python img arm64 based

So far, I have not done any testing inside Docker containers.

Just for more context because i did'nt quite understand what you wrote up there,

you're setting up the lib like this?

self.driver = Chrome(
    options=chrome_options,
    service=service,
    version_main=version_main,
    driver_executable_path=cPath
)

or more like this:

self.driver = Chrome(options=chrome_options, driver_executable_path=cPath)

???

[otomay]

I tried both (and more ways)

self.driver = Chrome(options=chrome_options)
#
self.driver = Chrome(options=chrome_options, driver_executable_path=cPath)
#
service = Service(cPath)
self.driver = Chrome(options=chrome_options, service=service)
#
service = Service(cPath)
self.driver = Chrome(options=chrome_options, driver_executable_path=cPath, service=service)
#
service = Service(cPath)
self.driver = Chrome(options=chrome_options, driver_executable_path=cPath, service=service, port=8002)
#
and so on

I'll try to run on docker on my x64 device and let you know if it works, 1s

don't pass service argument,

the Chrome class of this package does not accept it

[otomay]

yep, can confirm now
this works just fine on docker in a x64 machine (with chromium browser, not chrome):

  ua = UserAgent(platforms='desktop')
  chrome_options = ChromeOptions()
  chrome_options.add_argument('--headless')
  chrome_options.add_argument('--no-sandbox')
  chrome_options.add_argument('--lang=en')
  chrome_options.add_argument('--log-level=3')
  chrome_options.add_argument('--disable-extensions')
  chrome_options.add_argument('--disable-dev-shm-usage')
  chrome_options.add_argument('--window-size=1280x720')
  chrome_options.add_argument('--disable-notifications')
  chrome_options.add_argument('--no-first-run')
  chrome_options.add_argument("--disable-gpu")
  chrome_options.add_argument('--user-agent=%s' % ua.chrome)

  try:
      self.driver.quit()
  except:pass

  cPath = '/usr/bin/chromedriver' if os.path.exists('/usr/bin/chromedriver') else ''
  self.driver = Chrome(options=chrome_options, driver_executable_path=cPath)

but it doesn't work on arm64

but it doesn't work on arm64

I will investigate. By the way, you do not even need to pass driver_executable_path, it is optional.

Though, it follows a hierarchy: it will first look for Chrome binaries, then Chromium, then Chrome Beta, etc

[otomay]

cool, tysm, let me know if I can help testing

[carl0smat3us]

Interesting that it works on the GitHub runner with Windows 11 ARM
