decryptCallback is null on SecureCredentialsManager.checkAuthenticationResult

Hello, trying to implement Lock screen with Android Auth0.Lock lib. Not much provided on this topic (Auth0.Android Save and Renew Tokens). So before calling SecureCredentialsManager.getCredentials SecureCredentialsManager.requireAuthentication is called. Lock screen is showed as excepted. All good. Correct Fingerprint/pin code is provided. In onActivityResult getting excepted requestCode and resultCode is -1. But now in SecureCredentialsManager.kt:113 line decryptCallback is null, so return false is returned and Lock screen is prompted once again. Any advices where to check for the problem?

  • Which SDK this is regarding:
    “com.auth0.android:auth0:2.2.0”
    “com.auth0.android:lock:3.0.0”

Found it. SecureCredentialsManager was not Singleton.
