Omitempty for nlb obj in mcisAccessInfo not work

[seokho-son]

    Server response (Pretty JSON)

{
  "McisId": "mcis01",
  "McisSubGroupAccessInfo": [
    {
      "SubGroupId": "g1",
      "nlbListener": {
        "protocol": "",
        "ip": "",
        "port": "",
        "dnsName": "",
        "keyValueList": null
      },
      "McisVmAccessInfo": [
        {
          "vmId": "g1-1",
          "publicIP": "13.125.209.56",
          "privateIP": "192.168.20.133",
          "sshPort": "22",
          "privateKey": "-----BEGIN RSA PRIVATE KEY-----\n...\n-----END RSA PRIVATE KEY-----"
        },
        {
          "vmId": "g1-2",
          "publicIP": "43.201.72.240",
          "privateIP": "192.168.20.172",
          "sshPort": "22",
          "privateKey": "-----BEGIN RSA PRIVATE KEY-----\n...\n-----END RSA PRIVATE KEY-----"
        }
      ]
    }
  ]
}

해당 subgroup에 매치되는 NLB가 없는 경우

      "nlbListener": {
        "protocol": "",
        "ip": "",
        "port": "",
        "dnsName": "",
        "keyValueList": null
      },

이렇게 표시되는 상태인가보네용.. ㅎㅎ
