Invalid NEST response built from a unsuccessful low level call on POST

I want to configurate NEST from c# code When I use Kibana command GET /_cat/indices?v

I get this result:

enter image description here

My test index is "customer"

I'm using Elasticsearch.Net and NEST: the .NET clients [6.x] Elastic "6.5.4", Now this is how I configurate on C#:

  var settings = new ConnectionSettings(new Uri("http://localhost:9200"))
.DefaultIndex("customer");

        var client = new ElasticClient(settings);



        var newCustomer = new Customer
        {
            name = "test_name",
            OS = "test_os",
            script = "test_script"
        };


        var indexResponse = client.IndexDocument(newCustomer);

and I get an error:

Invalid NEST response built from a unsuccessful low level call on POST: /customer/customer

why does it build request to /customer/customer ??? What am I configurating wrong?

Error message:

Solution

  • You have already a mapping in ES and the document you want to index doesnot match with it.
