Unrecognized field "parentId"

When I cloned the repository today and try to use it, I could not load any entries into the catalogue but rather get: { "code": "conflict_error", "message": "Unrecognized field "parentId" (class org.keycloak.representations.idm.GroupRepresentation), not marked as ignorable (8 known properties: "clientRoles", "subGroups", "path", "attributes", "id", "realmRoles", "access", "name"])\n at [Source: (io.quarkus.vertx.http.runtime.VertxInputStream); line: 1, column: 71] (through reference chain: org.keycloak.representations.idm.GroupRepresentation["parentId"])" } Any idea how and when this will be fixed?
