Maybe you can try to clean up your project and run again


Please share us the execution log, some screenshot to help us investigate better.


Please check the project settings > Execution > Default execution

Possibly you have the Default execution is initialized with “Web Service”, which is the initial value set in the deliverable zip. Until v5.7.1 the default execution was initialized with “Chrome” but as of v5.8.0 it is “WebService”.

If you leave it to be “Web Servcice” and click the Green Run button GreenRunButton without selecting any browser (firefox, chrome, etc) , then you would have “Unable to open browser with url” message. Reason? well, you have not specified browser to choose.

You should change the Default execution setting to be your favorite browser unless you do Web Service testing frequently. Otherwise you need to explicitly specify Browser type to use everytime you run a Web UI test case.

Had the same issue where our tests are failing at open browser:

Error: :x: Unable to open browser with url: ‘’

Scrolled down to see:

Turns out my Chrome is still on version 73. Updated my Chrome and our tests are running again. :slight_smile:
Updated my Firefox as well for good measure. :smiley:

“Run from here” → “Chrome/Firefox” also its not working.

Whenever we try to execute from middle we selected browser also in right hand side panel its not showing Browser name.

And error also we are getting like “BrowserNotOpenedException”. Can you please help us to solve this issue. This issue happen after upgrade only

Works well on Eclipse.

Thanks for the feedback. I remedied the issue by updating Chrome and delete Katalon and re-extracted the files.

Hi @Sample,

We have fixed that issue, please update Katalon to v6.1.4. We are sorry for this inconvenient.

Please make sure that you create a project of type “web testing”.

Temp solution is run tc / ts in headless mode chrome or firefox than run normal, work ? yea why work like this ? idk XD u dnt need downgrade version

@Alojzius_Pendergast I’m sorry it’s not included. There were some dependency conflicts that we need to resolve.


thanks for your fast response.
Do you have info in which future version it will be included?
