I have configured Katalon Studio in my MacBook Pro. When I tried to launch my Android application in Katalon, it is showing - ‘Unable to capture objects. Reason: SWTException’ and the Exception is:

Failed to execute runnable (org.eclipse.core.runtime.AssertionFailedException: null argument:)

I am running Katalon Studio, Version: 5.8.6, Build 1.

How to fix the issue?

Which Appium version you are using? Looks like it is not the recommended one from our website: 1.8. In this case, please execute this command to downgrade and install Appium 1.8.1 instead:

npm install -g appium@1.8.1

Thanks

Thanks Vinh Nguyen. I have downgraded Appium. Now, I am not seeing the exception. It is loading Device View. But, strangely, it is blank. Refer attached screenshot.

The App is developed using React Native.
