i tried to check if an index exists or note before i do a search, i found a solution by performing requests, but it's not working, it results on a NullPointerException

```
   @Autowired
private RestHighLevelClient restHighLevelClient;

private List<E> convertToObjectList(SearchRequest searchRequest) {
	SearchResponse searchResponse = null;
	try {
		if (searchRequest != null) {
			RestClient restClient = null;
			Response response = restClient.performRequest("HEAD", "/" + index()); //java.lang.NullPointerException: null
			int statusCode = response.getStatusLine().getStatusCode();
			if (statusCode != 404) {
				searchResponse = restHighLevelClient.search(searchRequest);
			}
		}
	} catch (IOException e) {
		logger.error("Error" + e);
	}
	....
}

@Configuration
public class ElasticsearchConfiguration extends AbstractFactoryBean<RestHighLevelClient> {

	private RestHighLevelClient restHighLevelClient;

	@Override
	public RestHighLevelClient createInstance() {
		return buildClient();
	}

	@Override
	public Class<RestHighLevelClient> getObjectType() {
		return RestHighLevelClient.class;
	}

	@Override
	public void destroy() {
		try {
			if (restClient() != null) {
				restClient().close();
			}
		} catch (final Exception e) {
			logger.error("Error closing ElasticSearch client: ", e);
		}
	}

	@Override
	public boolean isSingleton() {
		return false;
	}

	public RestClient restClient() {
		return RestClient.builder(new HttpHost("localhost", 9200, "http")).build();
	}

	private RestHighLevelClient buildClient() {
		try {
			restHighLevelClient = new RestHighLevelClient(restClient());
		} catch (Exception e) {
			logger.error("Error" + e);
		}
		return restHighLevelClient;
	}

}
```

Well...

```auto
RestClient restClient = null;
Response response = restClient.performRequest("HEAD", "/" + index()); 

```

Don't you see anything obvious?
