Base64 in WrapperBuilder. co.elastic.clients

Hi Community,

I encountered strange behavior with a new Elasticsearch Java client.

Before, I used org.elasticsearch:elasticsearch:7:8:1
WrapperQueryBuilder wrapperQueryBuilder = new WrapperQueryBuilder("string") to get a wrapped query with Base64.

Now, I decided to use a new client co.elastic.clients:elasticsearch-java:7.17.22 and the same logic

WrapperQuery.Builder wrapperQueryBuilder =
              QueryBuilders.wrapper()
                      .query("string");

Unfortunately, I did not get the old result. It means I have to use Base64Encoder or use another builder to get Base64?

Have a look at

          {
              String matchAllQuery = Base64.getEncoder().encodeToString("{\"match_all\":{}}".getBytes(StandardCharsets.UTF_8));
              SearchResponse<Void> response = client.search(sr -> sr
                              .index(indexName)
                              .query(q -> q.wrapper(wq -> wq.query(matchAllQuery))),
                      Void.class);
              assertNotNull(response.hits().total());
              assertEquals(1, response.hits().total().value());
              assertEquals("1", response.hits().hits().get(0).id());
          }

Hope this helps.
