it's a simple question, but I can't seem to serialize the SearchResponse back to a json string.

What I've tried:

```auto
    final SearchResponse<ObjectNode> search1 = client.search(
            e -> e.index("myindex")
                    .query(

                                    qb -> qb.matchAll(ma -> ma)

                    )
            ,
            ObjectNode.class);
    final JsonGenerator generator = Json.createGenerator(response.getWriter());
    search1.serialize(generator, new JacksonJsonpMapper(createDefaultObjectMapper()));
    generator.close();

```

I get the non meaningful error:

```auto
java.lang.IllegalArgumentException: Jackson's ObjectMapper can only be used with the JacksonJsonpProvider

```
