Hello Friends, I am getting the below exception when I call userResource.search(..) api in keycloak-admin-client. I am using wildfly-swarm to secure my rest services. One of the stateless beans requires user details. So I am using keycloak-admin-client to get user info from the Keycloak Server (standalone 3.2.1.Final) . I have tried with admin-client 3.2.1.Final. I get the same error. What am i doing wrong? I think some deps are messed. But which ones? UserRepresentation is part of keycloak-core jar. I see the 3.4.0.Final jar as expected. Wildfly-swarm- 2017.11.0 keycloak-admin-client-3.4.0.Final keycloak server- 3.2.1.Final Please help. I am stuck and not able to proceed. Some pointers on the same would be very helpful. 2017-11-17 12:43:10,542 [default task-1 ] ERROR stderr - javax.ws.rs.client.ResponseProcessingException: javax.ws.rs.ProcessingException: com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "access" (class org.keycloak.representations.idm.UserRepresentation), not marked as ignorable (24 known properties: "disableableCredentialTypes", "enabled", "emailVerified", "origin", "self", "applicationRoles", "createdTimestamp", "clientRoles", "groups", "username", "totp", "id", "email", "federationLink", "serviceAccountClientId", "lastName", "clientConsents", "socialLinks", "realmRoles", "attributes", "firstName", "credentials", "requiredActions", "federatedIdentities"]) 2017-11-17 12:43:10,542 [default task-1 ] ERROR stderr - at [Source: org.apache.http.conn.EofSensorInputStream@519efa33; line: 1, column: 300] (through reference chain: java.util.ArrayList[0]->org.keycloak.representations.idm.UserRepresentation["access"]) Thanks a lot, Subhro.
