使用映射创建索引的问题

Question

我使用的是弹性搜索版本7.1.0和NEST 6.7.0以及ElasticSearch.NET 6.7.0。当我试图创建索引时，我出现了一个错误。

这是我的代码，我在NEST和ElasticSearch.NET 6.4.0版上使用了相同的代码，并且运行良好

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)
                    )
                )
            );

NEST和Elasticsearch.NET 6.7.0与ElasticSearch7.x不兼容。请使用NEST和ElasticSearch.NET 7.x，目前即将发布的最新版本是7.0.0-alpha2。
