How to convert a `hashmap` to `co.elastic.clients.json.JsonData` in new elasticsearch Java client API?

I am doing this conversion to provide the `document` to a `IndexRequest.Builder`.

```auto
IndexRequest.Builder<JsonData> request =
        new IndexRequest.Builder<JsonData>().index(indexName).id(1);
    request.document( ______ );

```

Is it required to convert the hashmap to Json string first, then to JsonData?  
or is there a way to directly convert hashMap to JsonData that can be feed to the IndexRequest?

You can create a `JsonData` object from any object that can be serialized to JSON using `JsonData.of(theMap)`.

Now in your use case you don't need `JsonData` and can also create `IndexRequest.Builder<HashMap<String, Something>>` and use `request.document(theMap)`.
