JsonReaderException为Elasticsearch创建批量索引

Question

This is my first attempt using elasticsearch. I'm not sure how to troubleshoot the JsonReaderException error below.

var result = client.Bulk(d => descriptor);

results in an exception error

An exception of type 'Newtonsoft.Json.JsonReaderException' occurred in Newtonsoft.Json.dll but was not handled in user code

Additional information: Error reading string. Unexpected token: StartObject. Path 'items[0].index.error', line 1, position 108.

var client = new ElasticClient();
client.DeleteIndex("Tracks");
client.CreateIndex("Tracks", c => c
.NumberOfReplicas(1)
.NumberOfShards(6)
.AddMapping<vw_MusicTracks>(m => m.MapFromAttributes()));

var descriptor = new BulkDescriptor();
var context = new MerchEntities();
var sqlTracks = context.vw_MusicTracks.ToList<vw_MusicTracks>();

foreach (var order in sqlTracks)
{
    descriptor.Index<vw_MusicTracks>(op => op.Index("Tracks").Document(order).Type("Track").Id(order.IMUTrackId));
}
    var result = client.Bulk(d => descriptor);
Console.WriteLine("job's done");
Console.ReadKey();

        public string Class { get; set; }
        public string GenreName { get; set; }
        public string ArtistName { get; set; }
        public string CityName { get; set; }
    }
}

将索引更改为所有小写字母即可解决此问题。
