Unable to Capture objects | ExecutionException | java.lang.NullPointerException

Hi @sekar.stickearn,

Yes, the versions you listed are incompatible. You can try Appium Server 1.8.1 to work with Katalon Studio 6.1.0.

Alternatively, you can try out the Katalon Studio 6.2.0.rc1 version which has experimental support for Appium 1.12:

Hope this helps,

Chris
