Problem description

This appears to be a duplicate issue that has been reported several times.
If it's an unintended error and If there's no one to work on this issue for now,
it okay for me to work on it?

Code

final BulkResponse response = client.bulk(br -> br.operations(
                    bo -> bo.index(io -> io.withJson(jsonInputStream).index("test").id("1"))
            ));
