Sort is broken

Running a search in Node with a sort is broken. I can run the exact same query with curl and it returns correctly. It looks like it may have something to do with the way the sort array is getting parsed as you can see below in the trace. I searched all over to see if I was doing something wrong, but maybe someone more skilled than me can take a look.

function runSearch() {
        esC.search({
            "query":{
                "bool":{
                    "must":[{
                            "query_string":{
                                "default_field":"UPDATE.user_id","query":"2f9633f8-3cc5-344b-bf71-fe0f78ae46da"}
                        }]
                }
            },
            "from":0,
            "size":50,
            "sort":[{ "timestamp" : {"order" : "desc", "ignore_unmapped" : true}}]
        }, function (err, res) {
            console.log(res);
        });
    }

I think this is still broken. Passing an object in as the elasticsearch rest api supports it does not get parsed to JSON correctly. Adding it to the “body” of the query and your results are not sorted. the sort field does work with simple strings passed in the array something like:

"sort": [ "date:desc", "title" ]

but not:

"sort": [ {"date": "desc"}, {"title": {"unknown_mapping":"keyword", "order": "desc"}} ]

You should send those values in the body of the request. In order to do that, they need to be placed under the body: key. See the second example here for an example.

Can you please copy old example? The link is broken and dont work anymore.

upd. Here it the schematic code:

client.search({
	index,
	type,
	body:{
		query: {...},
		sort: {...}
	},
	//and here other params like
	_source_includes,
	from,
	size,
	...
})

It’s strange, that the official document contains wrong description https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/6.x/api-reference.html#_search. For me, sort on the top level work only if i pass string or array of strings without direction.
