Yang Patch response

Testing out trying to use yang-patch (rfc 8072) for pushing two edits of the same service in one restconf call. I can get the yang-patch to work fine and it creates two services and commits them with the one call.

The problem I am running into is not getting a response from yang-patch. Per the RFC section 2.6:

If a YANG Patch is completed without errors, the RESTCONF server MUST
   return a "yang-patch-status" message with a "global-status" choice
   set to "ok".

   Refer to Appendix A.1.2 for an example of a successful YANG Patch
   response.

Currently with postman, curl, or python calls I am getting 500 internal errors.

 

Am I missing a step that will show the yang-patch-status? Attached is yang, below the restconf call.

RESTCONF: (Shell Curl)

curl --request PATCH \
  --url http://ncslab.com:8080/restconf/data/patch-service-test \
  --header 'Accept: application/yang-data+json' \
  --header 'Authorization: Basic daaaaaaaaaaaaa2Ux' \
  --header 'Content-Type: application/yang-patch+json' \
  --data 'service_patch.json'

service_patch.json

{
  "ietf-yang-patch:yang-patch": {
    "patch-id": "patch-1",
    "comment": "Test Patch responses",
    "edit": [
      {
        "edit-id": "edit1",
        "operation": "create",
        "target": "/",
        "value": {
          "patch-service-test:patch-service-test": [
            {
              "patch-service-test:circuit_id": "patch_yang_CID_1",
              "patch-service-test:name": "patch_description1",
              "patch-service-test:deviceName": "xe_virl",
              "patch-service-test:deviceID": "1111",
              "patch-service-test:deviceType": "cisco-ios",
              "patch-service-test:interfaceType": "GigabitEthernet",
              "patch-service-test:interfaceName": "0/0/0"
            }
          ]
        }
      },
      {
        "edit-id": "edit2",
        "operation": "create",
        "target": "/",
        "value": {
          "patch-service-test:patch-service-test": [
            {
              "patch-service-test:circuit_id": "patch_yang_CID_2",
              "patch-service-test:name": "patch_description2",
              "patch-service-test:deviceName": "xe_virl",
              "patch-service-test:deviceID": "1111",
              "patch-service-test:deviceType": "cisco-ios",
              "patch-service-test:interfaceType": "GigabitEthernet",
              "patch-service-test:interfaceName": "0/0/0"
            }
          ]
        }
      }
    ]
  }
}

The server just responds with the following:

500 Internal Server Error

 

Logs from NSO just show the service being created and a commit performed by rest.

Can more verbose logging be turned on or something added to the restconf call to get the response part working?
