{attributes=com.sailpoint.seaspray.transform.ConcatTransform@1e55313f}

That is my output when I try to use the in built transform: See below.
Any idea why this is going wrong? I’ve tried wrapping the concat in a static field but no change

"name": "TEST",
  "type": "decomposeDiacriticalMarks",
  "attributes": {
      "input": {
          "attributes": {
              "type": "concat",
              "attributes": {
                  "values": [
                      {
                          "type": "identityAttribute",
                          "attributes": {
                              "name": "preferredFirstName"
                          }
                      },
                      " ",
                      {
                          "type": "identityAttribute",
                          "attributes": {
                              "name": "lastname"
                          }
                      }
                  ]
              }
          }
      }
  }
