Bulk data failure

[wjfang90]

NEST/Elasticsearch.Net version 6.5.1:

Elasticsearch version 6.5.4

Description of the problem including expected versus actual behavior:
I used client.Bulk() method to save data to ES, responsed success, except _id had value,other fields had empty value, and no exception for me, any mistake with me?

Steps to reproduce:
my demo code

private void Test(){
         var index = "test";
         var key = "Gid";
        var bulkJobjectList2 = new List<JObject>() {
                            new JObject() {
                                    { "Gid","1" },
                                    { "Title","test index bulk many 1 width JObject" }
                                },
                            new JObject() {
                                  { "Gid","2" },
                                  { "Title","test index bulk many 2 width JObject" }                          
                                }
                        };        
          EsHelper.ClientSet.IndexMany(index, key, bulkJobjectList2);
    } 

EsHelper  class IndexMany method :

public static IBulkResponse IndexMany(this IElasticClient client, string index, string keyField, IEnumerable<JObject> res) {
            var response = client.Bulk(b =>
                                        b.Index(index)
                                        .Type(index)
                                        .IndexMany(res, (f, o) =>  
                                            f.Document(o)
                                            .Id(o[keyField].Value<string>())
                                            )
                                       );
            return response;
        } 

Expected behavior
data save success,but only _id had vlaue,others were empty.

Hi!

NEST 6.5.1 is a very old version and out of support..

How did you confirm your data was not written correctly? The bulk response does not return the full documents which means it's totally expected to only see _id and a few other meta fields.

The request looks good, so I assume your data is correctly written. You should try to request it in a second operation or manually check it in Kibana.
