[keycloak-user] NPE - logout

[java_os]

Hi - nullppointer on logout call
2.2.1.Final and 2.3.0.Final - Nullpointer when logging out using
keycloak.js (setup: Ng(keycloak.js) -> Rest. Idp login through KC identity
brokering to saml).
Below is the stacktrace - how do I logout from the SAML bridge? login works.

Anyone experienced this? It's happening on logout:
