Hi @vinay123,

when do you get the NPE (after which command, I don't think constructing the builders and the client will trigger it?) and how does it look like? Can you please attach a Stacktrace?

I don't exactly know what you want to do as I don't know which API you are calling.

If you want to do a GET document call, you are missing the document id. see [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-document-get.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-document-get.html)

```auto
GetRequest getRequest = new GetRequest("jsonvalidation", "1");
GetResponse getResponse = client.get(request, RequestOptions.DEFAULT);

```

If you want to do a GET index call, see [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-get-index.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-get-index.html)

```auto
GetIndexRequest request = new GetIndexRequest("jsonvalidation");
GetIndexResponse getIndexResponse = client.indices().get(request, RequestOptions.DEFAULT);

```

It's probably not supported.  
6.8 client might have this.
