问题
When I use both arguments --headless and user-data-dir. Selenium raise selenium.common.exceptions.WebDriverException: Message: unknown error: DevToolsActivePort file doesn't exist exception. If only 1 of them is used, then everything works as needs.
I tried to swap arguments and remove some of them. Specified the full path to chromedriver.exe. None of this helped.
chromeOptions.add_argument("--disable-dev-shm-using") DIDN'T HELP ME.
login = "test"
chromeOptions = webdriver.ChromeOptions()
chromeOptions.add_experimental_option("prefs", {"profile.managed_default_content_settings.images": 2})
chromeOptions.add_argument("--no-sandbox")
chromeOptions.add_argument("--disable-setuid-sandbox")
chromeOptions.add_argument("--disable-dev-shm-using")
chromeOptions.add_argument("--disable-extensions")
chromeOptions.add_argument("--disable-gpu")
chromeOptions.add_argument("start-maximized")
chromeOptions.add_argument("disable-infobars")
chromeOptions.add_argument("--headless")
chromeOptions.add_argument(r"user-data-dir=.\cookies\\" + login)
b = webdriver.Chrome(chrome_options=chromeOptions)
b.get("https://google.com/")
b.quit()

I solve it by adding an argument --remote-debugging-port=<port>
login = "test"
chromeOptions = webdriver.ChromeOptions()
chromeOptions.add_experimental_option("prefs", {"profile.managed_default_content_settings.images": 2})
chromeOptions.add_argument("--no-sandbox")
chromeOptions.add_argument("--disable-setuid-sandbox")
chromeOptions.add_argument("--remote-debugging-port=9222") # this
chromeOptions.add_argument("--disable-dev-shm-using")
chromeOptions.add_argument("--disable-extensions")
chromeOptions.add_argument("--disable-gpu")
chromeOptions.add_argument("start-maximized")
chromeOptions.add_argument("disable-infobars")
chromeOptions.add_argument("--headless")
chromeOptions.add_argument(r"user-data-dir=.\cookies\\" + login)
b = webdriver.Chrome(chrome_options=chromeOptions)
b.get("https://google.com/")
b.quit()
