Serilog 记录器 - 未找到请求的值 'True'

Question

调用 Serilog.Log.Logger():

时出现此错误

这是 .NET Core 2.1

System.ArgumentException: Requested value 'True' was not found.

我的Program.cs:

public class Program
{
    private static IConfiguration Configuration => new ConfigurationBuilder()
        .SetBasePath(Directory.GetCurrentDirectory())
        .AddJsonFile("appsettings.json", false, true)
        .AddJsonFile(
            $"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT")}.json",
            true, true)
        .AddEnvironmentVariables()
        .Build();
        
    public static void Main(string[] args)
    {
        Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(Configuration).CreateLogger();

        try
        {
            Log.Information("Web hosting is starting up.");
            CreateWebHostBuilder(args).Build().Run();
        }
        catch (Exception ex)
        {
            Log.Fatal(ex, "A fatal exception has forced unexpected host termination.");
            throw;
        }
        finally
        {
            Log.Information("Web hosting is shutting down.");
            Log.CloseAndFlush();
        }
        CreateWebHostBuilder(args).Build().Run();
    }

    public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>();
}

appsettings.json

{
    "Logging": {
        "LogLevel": {
            "Default": "Warning"
        }
    },

            }
    },
    "WriteTo": [

                "autoRegisterTemplate": true,
                "autoRegisterTemplateVersion": true
            }
        }
    ],
    "Enrich": [
        "FromLogContext",

        "WithEnvironmentUserName"
    ],
    "Properties": {
        "Application": "{myappname}"
    }
}

Answer 1

"autoRegisterTemplateVersion": true

问题与 appsettings.json 文件中的 autoRegisterTemplateVersion 参数有关。

从Serilog.Sinks.Elasticsearch JSON appsettings.json configuration可以看出autoRegisterTemplateVersion参数应该是字符串类型：

将 autoRegisterTemplateVersion 参数值从 true 更改为 "ESv2" 后，问题消失。
