Hello:

I am trying to use Elastic Java Client 8.8.0 (also known low-level rest client) and getting the error: `status: 200, [es/search] Failed to decode response`

I used the same library to create a new index and insert a new document and using the same POJO class to deserialize the document, found in the index, however no avail.

Here's the code fragment:

````plaintext
        patDocument.setAddendum("abc");
        patDocument.setDocumentName("docName");
        patDocument.setAuthorName("RK");
        patDocument.setId(3);
        try {
            IndexResponse response = esClient.index(i -> i
                    .index("patdocument-xxx")
                    .id(patDocument.getId() + "")
                    .document(patDocument)
            );
        } catch (IOException e) {
            System.err.println(e.getMessage());
        }

        // ======= searching documents =======
        SearchResponse<PatDocument2> response3=null;

        try {
            response3 = esClient.search(s -> s.index("patdocument-xxx")
                    .query(q -> q.match(t -> t.field("id").query("3"))), PatDocument2.class);
        } catch (IOException e) {
            System.err.println(e.getMessage());
        }
        System.out.println(response3);```

and this is the part of POJO:

````

```
private String addendum;
private String authorName;
private String documentName;
private Boolean draft;
private Integer id;

```

```auto

Thanks a lot in advance.

Kindly,

Roman
```

Are there any source code examples (perhaps on github) that uses mvn or gradle for Elastic Java Client library (perhaps I am missing the proper version of some library or so).

These are the libraries I am including:

I was able to solve the problem by using there libraries, I wish there would be some doco that outline exactly what libraries had to be included.

Here's the list:

- commons-logging-1.2.jar
- elasticsearch-java-8.9.0.jar
- elasticsearch-rest-client-8.9.0.jar
- httpasyncclient-4.1.5.jar
- httpclient-4.5.14.jar
- httpcore-4.4.13.jar
- httpcore-nio-4.4.16.jar
- jackson-annotations-2.15.2.jar
- jackson-core-2.15.2.jar
- jackson-databind-2.13.3.jar
- jakarta.json-api-2.1.2.jar
- jakarta.json.bind-api-2.0.0.jar
- parsson-1.0.0.jar

Yes. And with a dependency manager you normally don't have to add manually your libs.

But that's a good point. @swallez do you think we can generate the dependency tree automatically and add this to the documentation?

mvn dependency:tree does a pretty good job.
