Template for Event Action unsupported?

[superc254]

i copy this code in my config:

{
  "request": {
    "uri": "/event"
  },
  "response": {
    "text": "event"
  },
  "on": {
    "complete": {
      "post": {
        "url": "http://localhost:12306/target",
        "content": {
          "template": {
            "with": "${target}",
            "vars": {
              "target" : "target"
            }
          }
        }
      }
    }
  }
}

and i got this message:
