ElasticSearch .NET DateTime parse failed

[Schrader (Philipp)]

I want to parse my Json-Log into Logstash -> ElasticSearch and use it in my .Net-Core Application with NEST / ElasticSearch.NET.

My Log-File:

{"LogDate:":"2018-01-07T16:17:00.171Z", "ID":"1","LogLevel":"WARNING"}

My logstahs-config:

input 
{ 
  file
  {
   path => "C:/Log/ESTest/*.json"
   ignore_older => 86400
   start_position => "beginning"
  }
}

filter
{
  json
  {
   source => "message"
  }
}

output 
{
  stdout { codec => rubydebug }
  elasticsearch 
{ 
    index => "log"
    hosts => ["localhost:9200"]
    }
}

Console-output shows, that the fields got parsed well.

{
"path" => "****",
"LogLevel" => "WARNING",
  "@version" => "1",
   "message" => "{\"LogDate:\":\"2018-01-07T16:17:00.171Z\", \"ID\":\"1\",\"LogLevel\":\"WARNING\"}\r",
        "ID" => "1",
"@timestamp" => 2018-03-13T13:44:04.879Z,
  "LogDate:" => "2018-01-07T16:17:00.171Z",
      "host" => "****"
}

Even in Kibana, i saw, that every field from this JSON-string got parsed. If i go to my .NET-Core Application and crete my Query to get my Log (just an Example).

public class log
  {
      public DateTimeOffset LogDate { get; set; }
      public int ID { get; set; }
      public string LogLevel { get; set; }
      public Guid GUID { get; set; }
      public string Path { get; set; }
      public string Order { get; set; }
      public string Host { get; set; }
  }

var search = client.Search<log>(s => s         
.AllTypes()
.Index("log")  
.From(0)
.Size(1000)
 );

Each Value was parsed, except the LogDate-field. LogDate is empty and after i try to change the type of Log Date, the effect stay the same.

LogDate {01.01.0001 00:00:00 +00:00}    System.DateTimeOffset
LogDate {01.01.0001 00:00:00}   System.DateTime (type was changed)

My fault!

"LogDate:":"2018-01-07T16:17:00.171Z"

to

"LogDate":"2018-01-07T16:17:00.171Z"
and its working like a charm.
