Describe the bug

When I add .Enrich.WithElasticApmCorrelationInfo() to the LoggerConfiguration, I get the following error.

2023-07-24T22:34:37.2447202Z Caught exception while emitting to sink Serilog.Sinks.SystemConsole.ConsoleSink: System.NullReferenceException: Object reference not set to an instance of an object.
   at Elastic.CommonSchema.Serilog.LogEventConverter.GetService(LogEvent logEvent)
   at Elastic.CommonSchema.Serilog.LogEventConverter.ConvertToEcs[TEcsDocument](LogEvent logEvent, IEcsTextFormatterConfiguration`1 configuration)

   at Serilog.Sinks.SystemConsole.ConsoleSink.Emit(LogEvent logEvent)
   at Serilog.Core.Sinks.SafeAggregateSink.Emit(LogEvent logEvent)

To Reproduce

Log.Logger = new LoggerConfiguration()
    .MinimumLevel.Debug()
    .MinimumLevel.Override("Microsoft", LogEventLevel.Error)
    .MinimumLevel.Override("Elastic", LogEventLevel.Error)
    .Enrich.WithElasticApmCorrelationInfo()
    .WriteTo.Console(new EcsTextFormatter())
    .CreateLogger();

var builder = WebApplication.CreateBuilder(args);
    builder.Host.UseElasticApm();
    builder.Host.UseSerilog();

Expected behavior

A clear and concise description of what you expected to happen.

    var app = builder.Build();
    app.UseElasticApm();

Moved this over to elastic/ecs-dotnet

Thanks for bringing this to our attention @sgtobin!

I think the issue is the same as 324

[Mpdreamz]

I believe this was fixed in: https://github.com/elastic/ecs-dotnet/pull/306 will do a 8.6.1 release today.

Many thanks for reporting this!
