Hi all,

Need your help.

I have integrated Camunda BPM in my spring boot application with MySQL (to store Camunda varibales and data) and elasticsearch (to store real business application data), and it was working file.

**Now I have decouple the camunda server from spring boot application and deploying spring boot application through Camunda inbuilt Apache Tomcat server which is throwing NullPointerException in RestHighLevelClient**

In Below line **restHighLevelClient is reference of RestHighLevelClient which is throwing NPE:**

```auto
restHighLevelClient.fetchUnProcessedDocuments()

```

below is my RestHighLevelClient bean:

```auto
@Bean
public RestHighLevelClient getRestHighLevelClient() {

    HttpHost[] httpHost = {new HttpHost("localhost", 9200, "http")};
    RestClientBuilder restClient = RestClient.builder(httpHost);

    final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
    credentialsProvider.setCredentials(AuthScope.ANY,
            new UsernamePasswordCredentials("elastic", "test"));

    restClient.setHttpClientConfigCallback(httpClientBuilder -> {
         httpClientBuilder.disableAuthCaching();
        return httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);
    });

    return new RestHighLevelClient(restClient);
}

```

And I have added @Configuration annotation on top of configuration class.

Need you expertise advice to fix this issue. Thanks in advance.
