Yang error 'no-address' child found when parsing interface config from ASR-920, OS16.7.1

I am using Netconf-Yang Python libraries, with a ASR-920, having an issue with yang parsing not recognizing the <no-address> tag the ASR920 sends as part of the response under tag when no ip is assigned on an interface.
ASR 920 OS version Fuji 16.7.1, (sysdescr at end of issue)

Expected Behavior

Yang parses the response and no error is thrown

Current Behavior

When RPC response received from ASR 920, an error is thrown 'Cannot find child 'no-address'

Steps to Reproduce

Using netconf-yang, run crud_service.read_config against ASR920 with OS 16.7.1

 try:
      netconf = NetconfServiceProvider(
          address     = host_dict["ip_address"],
          port        = host_dict["netconf_port"],
          username    = host_dict["ssh_login"],
          password    = host_dict["ssh_password"],
          protocol    = host_dict["access_method"],
      )
    except Exception as error:
      self.log.error( "failed to connect via netconf to [%s] - exception: %s" %
        ( host_dict["ip_address"], error )
      )

    if not netconf:
      response_list = [
        408,
        ( 'Failed to connect via netconf to [%s]' % host_dict["ip_address"] ),
        {}
      ]
      return ( response_list, None )

    crud_service = CRUDService()
#test to get config fro GigabiteEthernet0/0/0 
    native = Cisco_IOS_XE_native.Native()
    gigabitethernet = native.interface.GigabitEthernet()
    gigabitethernet.name = '0/0/0'

    #self.log.info( pref + 'loading with filter: ' + dump.object( native ) )
    native.interface.gigabitethernet.append(gigabitethernet)
