I write test data to kibana through Csharp's serilog. Here is my code:  
using System;  
using Serilog;  
using System.Threading;

namespace SerilogTest  
{  
class Program  
{  
static void Main(string args)  
{  
Log.Logger = new LoggerConfiguration().MinimumLevel.Debug().Enrich.WithProperty("PlcSimulator", "Prod").  
WriteTo.LiterateConsole().WriteTo.Seq("[http://192.168.91.241:5000](http://192.168.91.241:5000)", compact: true).CreateLogger();

```
        for (int i = 0; i < 10; i++)
        {
            Random rd = new Random();
            int count = rd.Next(50, 100);
            Log.ForContext("当前在线数目", count).Information("show network info");
            Thread.Sleep(1000);
        }
        Log.CloseAndFlush();
    }              
}

```

}  
Now I have encountered a record with errors such as Tags: "Jiu jsonparsefailure message: keep alive" on kibana's discover page when writing data. Please tell me how to solve this problem
