Are you using an external Keycloak instance?

The issue appears to be caused by LiveOak expecting Client Scope mappings to be present in Keycloak, and they're not, which is why we see the NPE

[zohen]

I use internal Keycloak (http://localhost:5000/auth/admin/). All added clients are presents in Keycloak, but not presents at LiveOak.
