When trying to run slice of my app in Slice Viewer I have the following NPE exception. I followed this guide https://developer.android.com/guide/slices/getting-started and this one https://www.androidauthority.com/android-slices-872250/ . If I move all the code (provider, broadcast receiver) to Slice Viewer project slice is working fine. I do not see permissions request to access slice of my app. Any ideas? I use Slice Viewer 1.0.1
