Secret getPayload() openstack4j

Hi, I'm unable to get the secret's payload from openstack4j, it always returns null. Secret secret = os.barbican().secrets().get("19cbc4e8-cd06-450b-aa5d-2a4d20bf7d60"); secret.getPayload(); //Always returns null The same works when using the OpenStack CLI, openstack secret get --payload_content_type 'application/octet-stream' --file secret-payload http://x.x.x.x:9311/v1/secrets/19cbc4e8-cd06-450b-aa5d-2a4d20bf7d60 I'm using the below OpenStack4j version, Bundle-Name: OpenStack4j Core Bundle-Version: 3.6.0 OpenStack is in Queens version. Let me know if someone can help on this. Regards, Srini
