[keycloak-user] NPE after importing master realm/Keycloak 1.9.2

[Bystrik Horvath]

Hi,

I'm facing NullPointerException when log-in to security admin console after
importing the master realm.
I just wanted to access to master realm by SSL only, so I changed in
security admin console 'Require SSL' -to 'all requests' in the master realm
settings, saved and exported the master realm. After successful import -
using overwriting the existing strategy - I'm getting NPE after log-in to
master like follows below.
Is it a bug or do I do anything wrong by manipulating the master realm?

Best regards,
Bystrik
