Hello.

I am running into issues when using the updated logging lib.
I see the following runtime error:

Unhandled Exception: System.NotSupportedException: 
'AWS.Lambda.Powertools.Common.UniversalWrapperAttribute.WrapAsync[System.Threading.Tasks.VoidTaskResult](System.Func`2[System.Object[],System.Threading.Tasks.Task`1[System.Threading.Tasks.VoidTaskResult]],System.Object[],AWS.Lambda.Powertools.Common.AspectEventArgs)' is missing native code. MethodInfo.MakeGenericMethod() is not compatible with AOT compilation. 
Inspect and fix AOT related warnings that were generated when the app was published. 
For more information see https://aka.ms/nativeaot-compatibility

This seems to happen immediately at start up.
I am setting the logger on an .NET minimal API using

builder.Logging.ClearProviders();
builder.Logging.AddProvider(new LoggerProvider());

Where LogProvider is

using AWS.Lambda.Powertools.Logging;

public class LoggerProvider : ILoggerProvider
{
  public ILogger CreateLogger(string categoryName)
  {
    return Logger.Create(categoryName);
  }

  public void Dispose()
  {
    GC.SuppressFinalize(this);
  }
}

Any idea what could be the root cause?

Hey @JDurstberger what version are you using? Is this for an AOT enabled application?
The AOT version is still alpha, and I haven't tested yet with minimal apis AOT.

I was using 1.6.0-alpha with an AOT enabled application.
It looks to me like the serialization fails on messages logged by the minimal api itself.
