@RabBit_BR

Thank you for your reply.

I search in git and found this issue [null value in SearchResponse.hits.hits.sort causes parsing failure · Issue #66 · elastic/elasticsearch-java · GitHub](https://github.com/elastic/elasticsearch-java/issues/66)

It seems to be resolved in 7.16.2 according to this thread [Failure with sorts and new co.elastic.clients:elasticsearch-java client - #11 by swallez](https://discuss.elastic.co/t/failure-with-sorts-and-new-co-elastic-clients-elasticsearch-java-client/291511/11)

But I am using 7.17.4...it is still happening.

Hope @swallez can comment on this?
