HttpLoggingMiddleware breaks gRPC service response

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

If the HttpLoggingMiddleware gets used in aspnet core 6 hosting Rest API and gRPC service then the gRPC response message gets transparently removed.

The verbose logging of Grpc.AspNetCore.Server.ServerCallHandler logs following:

...
Sending message.
Serialized 'MyService.Protos.MyResponse' to 28 byte message.
Message sent.
Request deadline stopped.
Executed endpoint 'gRPC - /MyService/MyMethod'

The verbose logging of Grpc.Net.Client.Internal.GrpcCall logs following:

...
Reading message.
No message returned.
Message not returned from unary or client streaming call.
Call failed with gRPC error status. Status code: '"Internal"', Message: 'Failed to deserialize response message.'.
Finished gRPC call.
...
An unhandled exception has occurred while executing the request.
Grpc.Core.RpcException: Status(StatusCode="Internal", Detail="Failed to deserialize response message.")

Only the outgoing response message gets somehow removed by HttpLoggingMiddleware Disabling it resolves the issue instantly

Expected Behavior

HttpLoggingMiddleware should only log normal http requests and/or give more options to enable or filter gRPC logging

Steps To Reproduce

service configuration:

public void ConfigureServices(IServiceCollection services)
        {
          //... 
          services.AddGrpc(opt =>
            {
            });

           services.AddHttpLogging(logging =>
            {
                logging.LoggingFields = HttpLoggingFields.All;
                logging.RequestBodyLogLimit = 4096;
                logging.ResponseBodyLogLimit = 4096;
            });
}

Configuration

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                IdentityModelEventSource.ShowPII = true;

                app.UseHttpLogging();

                app.UseDeveloperExceptionPage();
                app.UseSwagger();
                app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "MyService API v1"));
            }
           //...

          app.UseEndpoints(endpoints =>
            {
                //...

                endpoints.MapGrpcService<MyService>()
                    .RequireHost("*:82", "*:443");

                endpoints.MapControllers();
            });
}

Exceptions (if any)

On the gRPC Client side, inside an rest api

An unhandled exception has occurred while executing the request.

Thanks for contacting us.

We’re moving this issue to the .NET 8 Planning milestone for future evaluation / consideration. We would like to keep this around to collect more feedback, which can help us with prioritizing this work. We will re-evaluate this issue, during our next planning meeting(s). If we later determine, that the issue has no community involvement, or it’s very rare and low-impact issue, we will close it - so that the team can focus on more important and high impact issues. To learn more about what to expect next and how this issue will be handled you can read more about our triage process here.

I’m also having the same issue. As a workaround, I’m avoiding the HttpLoggingMiddleware for gRPC requests

builder.UseWhen(
            ctx => ctx.Request.ContentType != "application/grpc",
            builder =>
            {
                builder.UseHttpLogging();
            }
        );
