[keycloak-user] Jackson Exception updating user password via REST

Hi, I recently upgraded from Keycloak 1.5 to 2.3.0.Final, and my previously working invocations of the "update password" REST API now fails on the Keycloak server with the following exception on the keycloak output. 16:09:50,970 ERROR [org.jboss.resteasy.resteasy_jaxrs.i18n] (default task-65) RESTEASY002005: Failed executing PUT /admin/realms/caewex/users/011aa181-45cd-4e34-95c1-5f0f23674b42/reset-password: org.jboss.resteasy.spi.ReaderException: com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "config" (class org.keycloak.representations.idm.CredentialRepresentation), not marked as ignorable (12 known properties: "period", "hashIterations", "digits", "hashedSaltedValue", "algorithm", "value", "temporary", "device", "createdDate", "salt", "type", "counter"]) at [Source: io.undertow.servlet.spec.ServletInputStreamImpl@157c188d; line: 1, column: 213] (through reference chain: org.keycloak.representations.idm.CredentialRepresentation["config"]) Any idea what I might be doing wrong?
