Failed to start Chromedriver

[wanderingkoala]

Hey Jacob, I was trying to run the Undetected Chrome driver on your sample colab file. Seems like it's running into a problem. I was hoping you could help fix the issue. Here's the error message I'm getting.

/usr/local/lib/python3.10/dist-packages/undetected_chromedriver/patcher.py in fetch_package(self) 286 logger.debug("downloading from %s" % download_url) --> 287 return urlretrieve(download_url)[0] 288

HTTPError: HTTP Error 404: Not Found

The above exception was the direct cause of the following exception:

It appears as though the regular version of Selenium works fine and it's just an issue with undetected-chromedriver. There is an issue (and pull request) on the undetected ChromeDriver repository covering the same problem: https://github.com/ultrafunkamsterdam/undetected-chromedriver/issues/1743

For now I'd recommend changing this line of code:

driver = gs.UndetectedChrome()

to:

driver = gs.ChromeDriver()

If you still want to use undetected-chromedriver before this error is resolved, you can monkey patch the problematic function like such:

from google_colab_selenium import UndetectedChromeDriver
from undetected_chromedriver import Patcher
from urllib.request import urlretrieve

def new_fetch_package(self):
    """
    Monkey patch implementing temp fix via this pull request:
    https://github.com/ultrafunkamsterdam/undetected-chromedriver/pull/1745/files#diff-69fd64debbe3fad18a48b33169f3f1c5cd2afe469e6664bde6645838ef13810e
    """
    zip_name = f"chromedriver_{self.platform_name}.zip"
    if self.is_old_chromedriver:
        download_url = "%s/%s/%s" % (self.url_repo, self.version_full.vstring, zip_name)

    else:
        zip_name = zip_name.replace("_", "-", 1)
        download_url = "https://storage.googleapis.com/chrome-for-testing-public/%s/%s/%s"
        download_url %= (self.version_full.vstring, self.platform_name, zip_name)

    return urlretrieve(download_url)[0]

Patcher.fetch_package = new_fetch_package
driver = UndetectedChromeDriver()

driver.get('https://www.google.com')
print(driver.title)
driver.quit()
