Unable to capture objects: java.lang.NullPointerException error thrown when using Mobile Recorder. Please see screenshot below.

Appium version: 1.9.1
Katalon Studio version: 5.8.4 Build 14

The app is open and running on the iPad but the _Device Viewer _throws the NullPointerException error. Please help. How do I go past this error?

Hi Rushan,

Unfortunately, I don’t think Katalon Studio 5.8.4 supports Appium 1.9.1 yet. Can you downgrade to Appium 1.8.1 and try again? Also note that Katalon doesn’t support Xcode10 yet, either, so you’ll need 9.4.1 or earlier installed.

Hope this helps,

Chris

Hi Chris,

Thanks for that. I have now installed Appium 1.7.0 and downgraded Xcode to 9.3. Works now. Totally off topic this but any idea when Katalon Studio will support ios 12?

Thanks to @Frank_Keefer for pointing out that you can use Appium 1.8.2-beta to work with Xcode10 and iOS12 devices:

npm install -g appium@1.8.2-beta.
