Testing in MS Edge fails


When i try to run any test in the Microsoft Edge browser, i get the following error. I’ve made sure that the Katalon Studio web driver for edge matches the driver on my machine.

Test Cases/Test1 FAILED because (of) (Stack trace: com.kms.katalon.core.exception.StepFailedException: Unable to open browser with url: '' (Root cause: org.openqa.selenium.WebDriverException: Unable to parse remote response: Unknown errorBuild info: version: '3.7.1', revision: '8a0099a', time: '2017-11-06T21:07:36.161Z'System info: host: 'DESKTOP-HTPVMFO', ip: '', os.name: 'Windows 10', os.arch: 'amd64', os.version: '10.0', java.version: '1.8.0_181'Driver info: driver.version: CEdgeDriver)


The error states the URL is empty or Null…

Where is the URL defined in your scripts?


In the project when i created it. If i launch in Fireforx or Chrome it works fine. It is only in Edge it fails.


I’m currently having the same issue, it worked previously then I had to change some config for another browser and it has stopped.
