im trying to create the following reversenested aggregate:-

```
 "attributetotal": {
          "reverse_nested": {}
  }

```

which works fine in cerebro, with the following:-

`.ReverseNested("attributecount", r => r)`

but it gets ignore in the Json sent.

I'm guessing you have to specify aggs within the reverse.

How can I achieve an empty ReverseNested aggregate?

Thanks
