Getting values from Elastic-Stack

Question

I'll initial get dates from elastic stack. At first just any data set, just to proof it works. I set up the connection and than I try to get a data set. I show you my code and the error message below. You got any suggestions where to look for the missing values? Thanks, Frank

            string elasticSearchConnectionString = configuration.GetConnectionString("ElasticSearchConnection");
            string elasticSearchIndex = configuration.GetValue<string>("ElasticSearchIndex");
            Uri uri = new Uri(elasticSearchConnectionString);
            ConnectionSettings settings = new ConnectionSettings(uri).DefaultIndex(elasticSearchIndex);
            ElasticClient = new ElasticClient(settings);
            IGetResponse<_doc> result = ElasticClient.Get<_doc>(1);

现在可以使用...：

在我的RecordsRepository.cs中进行搜索：

        var result = ElasticClient.Search<_doc>(document =>
            document
            .Query(q => q
                .Match(m => m
                    .Field(f => f.DataRecordId)
                    .Query(search)
                )
            )
        );

和_doc.cs：

public class _doc
{
    [JsonProperty("contextName")]
    public string ContextName { get; set; }

    [JsonProperty("resourceId")]
    public string ResourceId { get; set; }

    [JsonProperty("componentId")]
    public string ComponentId { get; set; }

    [JsonProperty("processStepId")]
    public string ProcessStepId { get; set; }

    [JsonProperty("dataRecordId")]
    public long DataRecordId { get; set; }

    [JsonProperty("timestamp")]
    public object Timestamp { get; set; }

    [JsonProperty("value")]
    public double Value { get; set; }
}
