[keycloak-user] NPE when requesting authorization

Hi guys, I got this error when requesting authorization on a resource: $ curl -X POST http://localhost:8080/auth/realms/waziup/protocol/openid-connect/token -H "Authorization: Bearer $USERTOKEN" -d "grant_type=urn:ietf:params:oauth:grant-type:uma-ticket&audience=api-server&permission=Sensortest#sensors:view" {"error":"server_error","error_description":"Unexpected error while evaluating permissions"} On the server side I get: 12:42:11,821 ERROR [org.keycloak.authorization.authorization.AuthorizationTokenService] (default task-16) Unexpected error while evaluating permissions: java.lang.NullPointerException at org.keycloak.authorization.util.Permissions.permits(Permissions.java:194) at org.keycloak.authorization.authorization.AuthorizationTokenService.authorize(AuthorizationTokenService.java:173) at org.keycloak.protocol.oidc.endpoints.TokenEndpoint.permissionGrant(TokenEndpoint.java:1124) at org.keycloak.protocol.oidc.endpoints.TokenEndpoint.processGrantRequest(TokenEndpoint.java:190) at sun.reflect.GeneratedMethodAccessor449.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) I got my token this way: USERTOKEN=`curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d 'username=guest&password=guest&grant_type=password&client_id=api-server&client_secret=xxx' "http://localhost:8080/auth/realms/waziup/protocol/openid-connect/token" | jq .access_token -r` This seems to happen for scope-based policies.
