Sorting with a specified fieldname works. But Is there any way I can use a variable name to provide the sorting field. For example:

This works:  
"sort": [

```
   {

     "venue.price": {
       "order": "asc",
       "missing" : "_last"

```

}  
}

BUT this below doesnt:  
let varsort="venue.price";

```
"sort": [

   {

     "field":varsort,
       "order": "asc",
       "missing" : "_last"

     

   }
  }

```

Above gives me error No enum constant org.elasticsearch.search.sort.SortOrder.VENUE.PRICE.TIER"  
I have tried replacing "field" with "by", same problem.
