This version of ChromeDriver only supports Chrome version 114

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot connect to chrome at 127.0.0.1:62675
from session not created: This version of ChromeDriver only supports Chrome version 114

I'm getting this error when running python flathunt.py

What is the easiest way to resolve this issue? I'm using Chrome version 116, so should I simply downgrade?

Hey @silasburger,

This issue often comes up when there's a new version of Chrome. You can try clearing your Webdriver Manager cache (~/.wdm) and see if that clears up the issue. You shouldn't need to downgrade.

I just saw this message on my machine too. In my case, I have both Chromium and Google Chrome installed, and they are currently at different versions. This seems to confuse the version detection (and I don't exactly know why yet). But bringing your Chrome and Chromium versions inline, or uninstalling one of them, might help.

This comment fixed it for me: ultrafunkamsterdam/undetected-chromedriver#1491 (comment)

in chrome_wrapper.py change the code to:

def get_chrome_driver(driver_arguments):
    """Configure Chrome WebDriver"""
    logger.info('Initializing Chrome WebDriver for crawler...')
    driver_exec_path = ChromeDriverManager().install()
    chrome_options = uc.ChromeOptions() # pylint: disable=no-member
    if driver_arguments is not None:
        for driver_argument in driver_arguments:
            chrome_options.add_argument(driver_argument)
    chrome_version = get_chrome_version()
    driver = uc.Chrome(driver_executable_path=driver_exec_path, version_main=chrome_version, options=chrome_options) # pylint: disable=no-member

    driver.execute_cdp_cmd('Network.setBlockedURLs',
        {"urls": ["https://api.geetest.com/get.*"]})
    driver.execute_cdp_cmd('Network.enable', {})
    return driver

Okay. Linking this to #439 . There seems to be an issue with undetected_chromedriver for versions of Chrome beyond 114 right now. Looks like some change in the release process at Google - there's a PR in undetected_chrome that hasn't yet been merged: ultrafunkamsterdam/undetected-chromedriver#1478 . Until that's in, either downgrade to 114, or apply some of the patches in the undetected_chromedriver issues threads.

u can use
hansalemaos 's auto downloader , it fixes the issue, and it works.

I patched it to work for OSX as well, prob works for linux and windows as well.

ultrafunkamsterdam/undetected-chromedriver#1491

from auto_download_undetected_chromedriver import download_undetected_chromedriver
import undetected_chromedriver as uc

folder_path = "./"
chromedriver_path = download_undetected_chromedriver(folder_path, undetected=True, arm=False, force_update=True)
driver = uc.Chrome(driver_executable_path=chromedriver_path)

use any path as a destination folder, you can even put "./" for the current script's folder 👍

For Mac Arm users, just download Chromium 114. It worked again for me.

Before opening you might execute in terminal: xattr -cr /Applications/Chromium.app

Just merged #454, which bumps undetected-chromedriver to a version that should support the latest chrome. Please retest and check if this resolves your issues - thanks!

[Silas Burger]

I retested but I'm getting another error related to undetected_chromedriver.

[Arthur Taylor]

Hmm. Well, that's new. But I guess you could try converting the value passed in in chrome_wrapper so that it's explicitly parsed as an int before it goes into undetected_chromedriver. Does that fix your issue?

[Silas Burger]

That did fix my issue 🤷

[Arthur Taylor]

Please send a PR :)

[Silas Burger]

Sent 👍 (failed tests)

[Arthur Taylor]

Should be resolved by #460
