NSInternalInconsistencyException Cannot set the result on a completed task

Question

Getting this crash sometimes, while trying to sign in. Using Amplify pod version 1.0.5. This was preceded by (1) auth session expired, (2) password reset. Probably, something left not cleaned up. What I am looking for is, are there any additional debugs I can enable in AWS/Amplify SDK?
