Undetected Chromedriver, AttributeError: 'ChromeOptions' object has no attribute 'headless'

I'm getting an error when I run a Python Selenium script to open a webpage. I have tried uninstalling and reinstalling selenium, chromeautoinstaller, and undetected chromedriver. I also tried adding option.add_argument('--headless'). None of these were successful and the error remained the same.

Here is my code:

    def driverInit():
        option = uc.ChromeOptions()
        option.add_argument("--log-level=3")
    
        prefs = {"credentials_enable_service": False,
                 "profile.password_manager_enabled": False,
                 "profile.default_content_setting_values.notifications": 2
                 }
        option.add_experimental_option("prefs", prefs)
        driverr = uc.Chrome(options=option)
        return driverr
    
    def driverInitBuffMarket():
        option = uc.ChromeOptions()
        option.add_argument(
             rf'--user-data-dir=C:\Users\{os.getlogin()}\AppData\Local\Google\ChromeBuff\User Data')  # e.g. C:\Users\You\AppData\Local\Google\Chrome\User Data
        option.add_argument(r'--profile-directory=Default')
        driverr = uc.Chrome(options=option)
        return driver

The error occurs in the second-to-last line, driverr = uc.Chrome(options=option)

Here is the error:

Any help is greatly appreciated!

As of today, undetected-chromedriver is still using options.headless in their code.

That's a problem due to this change in selenium 4.13.0 that was just released:

* remove deprecated headless methods

Here are some alternatives:

• Downgrade to an earlier selenium version until fixed.
• Use SeleniumBase's UC Mode (a modified fork of undetected-chromedriver):

from seleniumbase import Driver
import time

driver = Driver(uc=True)
driver.get("https://nowsecure.nl/#relax")
time.sleep(6)
driver.quit()

Here's another, more advanced example with retries and clicks (using the SB() manager):

from seleniumbase import SB

with SB(uc=True) as sb:
    sb.driver.get("https://nowsecure.nl/#relax")
    sb.sleep(2)
    if not sb.is_text_visible("OH YEAH, you passed!", "h1"):
        sb.get_new_driver(undetectable=True)
        sb.driver.get("https://nowsecure.nl/#relax")
        sb.sleep(2)
    if not sb.is_text_visible("OH YEAH, you passed!", "h1"):
        if sb.is_element_visible('iframe[src*="challenge"]'):
            with sb.frame_switch('iframe[src*="challenge"]'):
                sb.click("span.mark")
                sb.sleep(4)
    sb.activate_demo_mode()
    sb.assert_text("OH YEAH, you passed!", "h1", timeout=3)
