Unable to get interface description with uniq

Using uniq to pull information from APIC-EM, But noticed that when pulling information regarding devices interfaces, don't see interface description. Using regular query works.

 from uniq.apis.nb.client_manager import NbClientManager

 client = NbClientManager(

    server="sandboxapic.cisco.com",

    username="devnetuser",

    password="Cisco123!",

    connect=True)

allHosts = client.networkdevice.getAllNetworkDevice()

allHosts = client.serialize(allHosts)

for host in allHosts['response']:

    print(host['id'])

    try:

        allInterfaces = client.interface.getInterfaceByDeviceId(deviceId = host['id'])

        allInterfaces = client.serialize(allInterfaces)

        for interface in allInterfaces['response']:

            print(interface['portName'])

    except:

        print("No information from device id: " + host['id'])

 Insted of "print(interface['portName'])"  want "print(interface['description'])" but it doesn't work.
