[🐛 Bug]: Unable to set user-data-directory AND chromedriver binary path at the same time: Error initializing WebDriver: Message: session not created from unknown error: unable to discover open pages #15087
Description
What happened?
When setting a custom user-data-directory AND chromedriver binary path at the same time: I get:
Error initializing WebDriver: Message: session not created from unknown error: unable to discover open pages
When removing the line options.add_argument(f"--user-data-dir={user_data_directory}") it runs fine.
When running without the custom executable path as service = Service() instead of service = Service(executable_path=chromedriver_binary_path) it runs fine while using the custom user-data directory and selenium manager chromedriver.
For my use case I need to be able to set both user-data-directory AND the custom binary path, however it seems when using both something is breaking. Am I doing something wrong here? I've exhausted every possible solution I could come up with.
Tested in chrome headless shell + chromedriver 132.0.6834.83.
Same setup config works fine with chrome non headless + chromedriver 132.0.6834.83.
How can we reproduce the issue?
Following is a snippet of my code:
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
chrome_binary_path = CC.get_chrome_binary_path(directory)
chromedriver_binary_path = CC.get_chromedriver_binary_path(directory)
user_data_directory = CC.get_user_data_directory()
# Initialize Chrome options
options = Options()
options.binary_location = chrome_binary_path
options.add_argument(f"--user-data-dir={user_data_directory}")
options.add_argument("--headless=new")
options.add_argument('--user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36')
options.add_experimental_option("prefs", {
"download.default_directory": directory,
"download.directory_upgrade": True,
"download.prompt_for_download": False,
"credentials_enable_service": False,
"profile.password_manager_enabled": False
})
options.add_argument('--start-maximized')
options.add_argument('--disable-notifications')
options.add_argument("--disable-third-party-cookies")
options.add_argument("--disable-dev-shm-usage")
options.add_argument("--no-sandbox")
options.add_argument("--disable-extensions")
options.add_experimental_option("excludeSwitches", ["enable-automation", "enable-logging"])
options.add_experimental_option("useAutomationExtension", False)
options.add_argument('--log-level=3')
service = Service(executable_path=chromedriver_binary_path)
# Initialize WebDriver with the given options and service
driver = webdriver.Chrome(service=service, options=options)
driver.quitRelevant log output
Error initializing WebDriver: Message: session not created
from unknown error: unable to discover open pages
