I am able to run the following query successfully

```auto
{
  "query": {
    "match_all": {}
  },
  "aggs": {
    "stadt": {
      "sum": {
        "script": "_index['title']['energy'].tf()"
      }
    }
  },
  "size": 0
}

```

But I dont want to enable `dynamic scripting` so I put the content of script into external file inside `es/config/scripts/tfscript.groovy`

Now the following query throws exception

```auto
{
  "query": {
    "match_all": {}
  },
  "aggs": {
    "stadt": {
      "sum": {
        "script": {
          "file": "tfscript"
        }
      }
    }
  },
  "size": 0
}

```

The exception is

```auto

```

I searched for `Unexpected token START_OBJECT in [stadt]` but could not figure out anything.  
Am I missing something basic here?
