However, when testing a basic functionality like “Object Sky” this popup always shows up. Already updated my chromedriver, my chrome browser, my java sdk to 1.8.0\_191. I also checked everywhere on the Katalon settings where to change the java compiler version, but didn’t find anything. Any ideas what else should I try?

Upvoted. I am having this problem as well, but strangely, only when executing a suite from Jenkins. I am able to execute local runs both from the GUI as well as from cmd, but the error in the OP is thrown when running from Jenkins. ---

I’ve found an approach that worked in my case, hopefully it will help others. After several hours of research, I’ve found that the general consensus in the Selenium community around this issue (it’s a recurring problem) is that there is some disagreement between the versions of each of these being used: 1.) Selenium 2.) ChromeDriver 3.) Chrome (browser) As Katalon Studio does its own management of the versions being used for each of these with each release, manually changing these is not a sustainable approach (although it can be done). The solution for me turned out to be from here: > Basically, I needed to add some custom args to chromedriver. This can be done as follows: 1.) In Katalon Studio, navigate to Project \> Settings \> Execution \> Default \> Web UI \> Chrome 2.) Add a row by clicking “Add” 3.) In the Name column, type “args” (without quotes) 4.) In the Type column, select “List” 5.) In the Value column, open up the List Property Builder by clicking on the elipsis button on the right. 6.) Add all of the following properties: ![](https://dub1.discourse-cdn.com/katalon/uploads/default/original/1X/913022cf88f8025cc70817a4e48973b234cba7eb.png) 7.) Apply the changes and see if the problem persists. [2018-11-27 11\_27\_10-List Property Builder.png](https://forum.katalon.com/uploads/short-url/kIomzvgjD6IPx74Wy1HpAzA1gT1.png) ---
