将索引 () 从 NEST 调度到 Elasticsearch.NET 失败

我在使用 Nest 和 Elasticsearch.NET 时调用client.Index时出错

var httpConnection = new AwsHttpConnection(new AwsSettings
{
    AccessKey = "AKIAIFIV4LN6XZAFVX7Q",
    SecretKey = "MySecretKey",
    Region = "us-east-1",
});
var pool = new SingleNodeConnectionPool(new Uri(sSearchURI));
var config = new ConnectionSettings(pool, httpConnection);
var client = new ElasticClient(config);
var person = new Person
{
    Id = "1",
    Firstname = "Martijn",
    Lastname = "Laarman"
};
var index = client.Index(person);

调度索引 （） 从 NEST 到 Elasticsearch.NET 失败
收到标记为 PUT 的请求此端点接受 POST，PUT 请求可能没有提供足够的信息来进行任何 这些端点：
-/{索引}/{类型}
-/{索引}/{类型}/{id}

知道吗？

settings.DefaultIndex("indexName");
