Attempt to invoke virtual method 'com.auth0.core.Connection com.auth0.lock.Configuration.getDefaultDatabaseConnection()' on a null object reference

[ritdaw]

We are seeing this on a few devices in Crashlytics. Using version 1.11.0. Note we are seeing this on a few Android 5.0/5.0.2 devices.

Still facing this issue. Using 'com.auth0.android:lock:1.16.+'.

[lbalmaceda]

@ulohani90 any steps to reproduce it? I'd suggest you either try the latest v1 dependency which is 1.18.+ or to migrate to v2 if possible. --> 2.5.0.

[ulohani90]

@lbalmaceda okay, let me try with 1.18.+.

[ulohani90]

Tried with 1.18.+. Still I am seeing some crashes in Crashlytics. I am not able to reproduce it at my end. But I do have the stack trace for the crash that Crashlytics has given me.
