That version of the client is not compatible with such an old Elasticsearch version. Have a look at [this thread](https://discuss.elastic.co/t/ccs-minimize-roundtrips-error-when-using-7-x-high-level-rest-api-to-access-6-x-index/194095) for a similar issue.

You need to either upgrade Elasticsearch to version 7.17 or downgrade the client to something compatible.
