So this is the cause. What version of KS are you using?The most likely cause is your driver not being the correct version - Download latest driver(chrome or IE) from seleniumhq.org, and use the below code

    System.setProperty("webdriver.chrome.driver","<YourPath>chromedriver.exe");
    WebDriver driver=new ChromeDriver();
    driver.get("http://www.yahoo.com");

I don’t fully understand what I don’t do. Would you be a little more prominent?

Ok first step, update to the latest version of Ks and make sure you have the latest version of chrome. If that doesnt work, let me know and ill provide the next step :slight_smile:

Hello Again , thank you crome and katalon studio latest version.
But project run ;

Nothing has changed as it was before.
The Chrome window is delivered but it still returns the same error.

Right Ok - Can you go into your katalon studio prefrences and make sure that this setting is ticked.

Yes but :

These are the two errors.

Caused by: org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

Caused by: java.lang.IllegalArgumentException: No enum constant

Im pretty much all out of ideas now, maybe @duyluong will be able to help you further

hello @duyluong @devalex88 Can you help me ?

Facing same issue while runing my test suit with azure pipline.

In case your browser is updated to a newer version, please use this command to update chromdriver: --config -webui.autoUpdateDrivers=true

Hi Emine,
