title: mget producing: Unable to parse response body for Response
body: <p>I'm issuing a <a href="https://www.elastic.co/guide/en/elasticsearch/client/java-rest/master/java-rest-high-document-multi-get.html" rel="nofollow noreferrer">Multi-Get request</a> via the Java High Level REST Client and I'm receiving the following exception:</p>
  
  <blockquote>
    <p>"Unable to parse response body for Response{requestLine=POST /_mget HTTP/1.1, host=<a href="http://localhost:9200" rel="nofollow noreferrer">http://localhost:9200</a>, response=HTTP/1.1 200 OK}"</p>
  </blockquote>
  
  <p>I pulled the following JSON from the logs that was sent to Elastic:</p>
  
  <pre><code>{
      "docs": [
          {
              "_index": "blah",
              "_type": null,
              "_id": "some-id-232332",
              "routing": null,
              "stored_fields": null,
              "version": -3,
              "version_type": "internal",
              "_source": {
                  "includes": [],
                  "excludes": []
              }
          }
      ]
  }
  </code></pre>
  
  <p>I sent the above JSON to Elastic via Postman and I'm seeing the following response (which is the same I see in the logs):</p>
  
  <pre><code>{
      "docs": [
          {
              "_index": "blah",
              "_type": null,
              "_id": "some-id-232332",
              "found": false
          }
      ]
  }
  </code></pre>
  
  <p>Isn't that a valid response?  Is this an issue w/ the elasticsearch-rest-high-level-client?</p>
