@MrBenjoo we are not able to reproduce this issue. It seems in your case the token received on callback is null and that is not the expected behavior. We have a PR out to capture the NPE and display the error, but in the mean time, is other social plugins like facebook working?

[MrBenjoo]

@banji180 I am getting the same exception after signing in with apple or facebook. Maybe it is unrelated, but i am seeing this in the logs each time the exception is thrown:

win=Window{1bf7804 u0 com.android.project/com.amplifyframework.auth.cognito.activities.CustomTabsManagerActivity} destroySurfaces: appStopped=true win.mWindowRemovalAllowed=false win.mRemoveOnExit=false win.mViewVisibility=4 caller=com.android.server.wm.ActivityRecord.destroySurfaces:5867 com.android.server.wm.ActivityRecord.destroySurfaces:5848 com.android.server.wm.ActivityRecord.notifyAppStopped:5912 com.android.server.wm.ActivityRecord.activityStopped:6554 com.android.server.wm.ActivityClientController.activityStopped:254 android.app.IActivityClientController$Stub.onTransact:596 com.android.server.wm.ActivityClientController.onTransact:130

[banji180]

ok thanks for the quick response, but I don't think this is the root cause. It seems the token is coming back as null, but since we are not able to reproduce, we are updating the SDK shortly to catch and display the token is null error. Once we release this update, we will update you.

We have released library version 2.2.2 to attempt to resolve this issue. Please let us know if that works for you!

[MrBenjoo]

@tjleing Yes, it seems that it works now. Thanks!
