Selenium Webdriverexception: Message: Unknown Error: Cannot Determine Loading Status From Unknown Error: Missing Or Invalid 'entry.level'

I have a script which uses selenium for testing. Now even opening a Google page using driver.get(url) # url = Google homepage url is giving me below error driver.get('https://my.g

Solution 1:

The error says it all :

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot determine loading status
from unknown error: missing or invalid 'entry.level'

Your main issue is the version compatibility among the binaries you are using as follows :

• You are using chromedriver=2.29.461591 (which is as per the logs, though you mentioned Chromedriver 2.35 in your question)
• Release Notes of chromedriver=2.29.461591 clearly mentions the following :

Supports Chrome v56-58

• You are using chrome=65.0.3315.3
• Release Notes of chromedriver=2.35 clearly mentions the following :

Supports Chrome v62-64

• You are using Selenium Version 2.53.1.
• Your JDK version is unknown to us.

Solution

• Upgrade JDK to recent levels JDK Version 8 Update 151.
• Upgrade ChromeDriver to ChromeDriver v2.35 level.
• Keep Chrome to Chrome v64.x levels. (as per ChromeDriver v2.35 release notes)
• Upgrade Selenium to current levels Version 3.8.1.
• Clean the Project Workspace from your IDE & Rebuild All.
• Run CCleaner tool to wipe off all the OS chores.
• If your Chrome base version is too old, uninstall Chrome through Revo Uninstaller and install a recent GA Release version of Chrome.
• Take a System Reboot.
• Execute your Test.

Solution 2:

Go to http://chromedriver.chromium.org/downloads

copy the download link according to your OS

wget -N paste_the_link_you_copied

unzip it using below command

unzip chromedriver_linux64.zip

Give the permission by the below command

chmod +x chromedriver

Then follow the below commands, if it says already exists (probabily old version) then go to that path (/usr/local/bin/chromedriver and /usr/bin/chromedriver) and delete chromedriver and run the commands again

sudo mv -f chromedriver /usr/local/share/chromedriver
sudo ln -s /usr/local/share/chromedriver /usr/local/bin/chromedriver
sudo ln -s /usr/local/share/chromedriver /usr/bin/chromedriver

Hope this helps. Thanks

Solution 3:

That error raised beacuse your chrome browser is not compatible with the web driver. If you are using Linux, then simply execute the following command. sudo apt-get update

Recently I am facing the same problem and take me too much time to figure out what's going on, in my situation facing the problem, I did not close the chrome process after using it, so you should check the process exit or not when you exit the app, this is my last worked Python 3 code demo, hope it will help others:

@staticmethod
    def fetch_music_download_url(music_name: str):
        chrome_driver_service = Service(ChromeDriverManager(chrome_type=ChromeType.GOOGLE).install())
        chrome_options = Options()
        chrome_options.add_argument("--no-sandbox")
        chrome_options.add_argument("--headless")
        chrome_options.add_argument("--disable-gpu")
        chrome_options.add_argument("--remote-debugging-port=9230")
        driver = webdriver.Chrome(service=chrome_driver_service,
                                  options=chrome_options,
                                  executable_path="/usr/local/bin/chromedriver")
        try:
            driver.maximize_window()
            driver.get('http://tool.example.cn/music/?page=audioPage&type=migu&name=' + music_name)
            driver.implicitly_wait(5)
            driver.find_element(By.CSS_SELECTOR, ".aplayer-list-download.iconfont.icon-xiazai").click()

            for url in urls:
                if "listenSong.do" in url:
                    logger.info("fetched url:" + url)
                    FetchMusic.do_save_music_download_url(url)
        except Exception as e:
            logger.error("scrapy impl error", e)
        finally:
            driver.stop_client()
            driver.close()
