I'm using elastic search version 7.1.0 and NEST 6.7.0 with Elasticsearch.Net 6.7.0. While I'm trying to create an index I've got an error.

This is my code, I was using the same code on NEST and Elasticsearch.Net version 6.4.0 and it was working fine

var result =   Client.CreateIndex(DefaultIndex, c => c
                .Settings(s => s
                    .NumberOfShards(numberOfShards)
                    .NumberOfReplicas(numberOfReplicas)
                    .BlocksReadOnly(false)
                )
                .Mappings(m => m
                    .Map<SearchDocument>(mm => mm
                        .AutoMap(3)
                    )
                )
            );

This is the error that I got
