[SOLVED] Selenium can't run Chrome with pre set profile on Ubuntu Jenkins

Issue

Trying to open specified chrome profile via selenium\python, but keep getting error

I feel like problem related to jenkins user, because i can run command as "tester" user "google-chrome --profile-directory=Norton --user-data-dir=/home/tester/selenium/google-chrome" and get into that profile. Without '--user-data-dir' option other tests runs well. Here is the code:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
import time 

chrome_options = Options()
chrome_options.add_argument('--window-size=1920,1080')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--disable-blink-features=AutomationControlled')
chrome_options.add_argument('--disable-automation')
chrome_options.add_argument('--disable-infobars')
chrome_options.add_argument('--ignore-ssl-errors=yes')
chrome_options.add_argument('--ignore-certificate-errors')
chrome_options.add_argument('--user-data-dir=/home/tester/selenium/google-chrome')
chrome_options.add_argument('--profile-directory=Norton')
chrome_options.add_argument('--incognito')
chrome_options.add_experimental_option('excludeSwitches', ['enable-automation'])
chrome_options.add_experimental_option('excludeSwitches', ['enable-logging'])
chrome_options.set_capability('pageLoadStrategy', 'eager')


driver = webdriver.Chrome(options=chrome_options)

I've tried replacing quotes, making new chrome dir for tests, headless mode. Checked that there is no chrome instances when test starts. Expecting that selenium will open on desired profile in incognito mode

Solution

Usually this error happens when running Selenium tests under any CI tool without setting the headless browser mode.

In this case, you need to add the following Chrome arguments:

chrome_options.add_argument("--headless")
chrome_options.add_argument("--disable-dev-shm-usage")
