Crash in the Smooch Android SDK

We've been getting this crash in the Smooch Android SDK for some time now:

         Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String io.smooch.core.service.SmoochService.l()' on a null object reference
     at io.smooch.core.f.c(SourceFile:1)
     at io.smooch.core.Smooch.getAuthorisationToken(:2)
     at io.smooch.ui.fragment.ConversationFragment.onCreateView(:54)
     at androidx.fragment.app.Fragment.performCreateView(Fragment.java:3119)
     at androidx.fragment.app.FragmentStateManager.createView(FragmentStateManager.java:577)
     at androidx.fragment.app.FragmentStateManager.moveToExpectedState(FragmentStateManager.java:286)
     at androidx.fragment.app.FragmentStore.moveToExpectedState(FragmentStore.java:114)
     at androidx.fragment.app.FragmentManager.moveToState(FragmentManager.java:1685)

There's no known way to reproduce it directly. Any ideas how to mitigate this?

Thanks!
