I'm trying to upload TOSCA model of a VF named 'underlayvpn' to the SDC using REST API.
After uploading successfully, I found some important information lost, such as: properties, attributes, requirements, capabilities. etc.
As far as I know, the 'underlayvpn' only has interface(node type definition), has no template(internal topology) in the use case of 'Volte'.
If it lost some important information, the design and deployment of the WAN network which is an important part of the Volte may be impact.

The URL of the upload request:

POST http://10.74.148.219:8080/sdc2/rest/v1/catalog/upload/multipart

The 'resourceMetadata' of the upload request:

{
  "payloadName": "underlayvpn.yml",
  "contactId": "jh0003",
  "name": "underlayvpn",
  "description": "underlayvpn desc.",
  "resourceIconPath": "compute",
  "resourceType": "VF",
  "categories": [
  {
    "name": "Volte",
    "subcategories": [
      {
        "name": "VolteVF"
      }
    ]
  }
],
  "tags": [
    "underlayvpn"
  ]
}

The 'resourceZip' of the upload request:
