I am using .Nest version 7.x and I am trying to post information to a remote elasticsearch log bridge. Using the following code:

```auto
                var object_test= new Dummy_Object{ 
                Dummy_String = "dummy_data",
                Dummy_Int = 3
               };
              ConnectionSettings settings = new ConnectionSettings(new Uri("https://base_url.com/v2/applications"))
                                                                    .BasicAuthentication("user_name", "password")
                                                                    .EnableDebugMode();
                ElasticClient client = new ElasticClient(settings);
                IndexResponse indexResponse = client.Index(new IndexRequest<Dummy_Object>(object_test, "index_IAm_Posting_To"));
                Console.WriteLine(indexResponse.DebugInformation);

```

Yet it does not work, I am not very experienced with using .NEST but have tested this index already and posted data to using this HTTP request:

```auto
https://base_url/v2/applications/index/log

```

Which submitted successfully, i've tested the uri without v2/application but it did not work. Here is the output I am looking at:

Invalid NEST response built from a unsuccessful (404) low level call on POST: `/v2/applications/index/_doc?pretty=true&error_trace=true`
