> [@dadoonet](#): > > GET my\_index/\_doc/1 Hi David, I am trying to extract the content that is stored under \_source. I came across GetSourceRequest in [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/master/java-rest-high-document-get-source.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/master/java-rest-high-document-get-source.html) But it is no longer present in `org.elasticsearch.client.core` From where Can I import GetSourceRequest? ---

I believe this is a new one which will become available in the 7.7 version. In the meantime you can use the GET document API and get the source with it. See [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.x/java-rest-high-document-get.html#java-rest-high-document-get-response](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.x/java-rest-high-document-get.html#java-rest-high-document-get-response) ---

Hi David, I tried using Get API .When I am trying to convert into a file and trying to open ,it is showing as below and i am unable to open it. ```auto Error Failed to load PDF document. ``` Here is what I have tried: ```auto @GetMapping("/getfile") public void getdata() throws IOException { String result="C:\\Users\\Documents\\pdfs\\x.pdf"; GetRequest getRequest = new GetRequest("twitter","_doc", "56"); GetResponse getResponse = client().get(getRequest, RequestOptions.DEFAULT); byte[] sourceAsBytes =getResponse.getSourceAsBytes(); File resultfile = new File(result); FileOutputStream fos = new FileOutputStream(resultfile); fos.write(sourceAsBytes); fos.flush(); fos.close(); } ``` I dont know where it is going wrong. ```auto String sourceAsString = getResponse.getSourceAsString(); ``` When I am trying to fetch source as string program terminates here. ---

You need to read the source, then access to the field where you stored the document in BASE64, then decode the BASE64 and generate the binary from this. ---

So As you mentioned the different approach by using 7.6 ,I installed 7.6 version and when I am trying to use the new version , it is showing ```auto master not discovered or elected yet, an election requires a node with id [eJcn6jOSRw65wy4liDC1VA], have discovered [{10INLPC0SP3TF} {1Farf6X-R1u0LM6KNgh4Kw}{4zM2-RhjSwaQxt15w3To9A}{127.0.0.1}{127.0.0.1:9300} ``` How to fix the above problem? ---

7.4 or 7.6 should behave the same. > [@samanvi\_sweety](#): > > So As you mentioned the different approach by using 7.6 ,I installed 7.6 version and when I am trying to use the new version , it is showing > > ```auto > master not discovered or elected yet, an election requires a node with id > [eJcn6jOSRw65wy4liDC1VA], have discovered [{10INLPC0SP3TF} > {1Farf6X-R1u0LM6KNgh4Kw}{4zM2-RhjSwaQxt15w3To9A}{127.0.0.1}{127.0.0.1:9300} > > ``` > > How to fix the above problem?

Does this have anything to do with version? ---
