[keycloak-dev] Failed to verify token: org.keycloak.common.VerificationException: Realm URL is null.

[Corinne Krych]

Hello Keycloak team,

I'm trying to move my OAuth2 demo app from Keyclaok 1.5 to Keyclaok 1.9.1.
I've change the OAuth2 endpoints for the access token. I manage the Oauth2
dansc ok but when trying to access a protected resource I hit the error:

22:00:13,501 ERROR [org.keycloak.adapters.BearerTokenRequestAuthenticator]
(default task-101) Failed to verify token:
org.keycloak.common.VerificationException: Realm URL is null. Make sure to
add auth-server-url to the configuration of your adapter!

My realm setup is here:
https://github.com/aerogear/aerogear-backend-cookbook/blob/master/Shoot/configuration/shoot-realm.json

The keycloak.json used for the protected endpoint is:
https://github.com/aerogear/aerogear-backend-cookbook/blob/master/Shoot/src/main/webapp/WEB-INF/keycloak.json

Is there some specific settings I should add to work with Keycloak 1.9.x?

Your help would be welcome.
