context.ResponseTrailers() not working?

[AnthonyGiretti]

I'm building a gRPC service.
I try validate data I receive and reply with an error like this:

public override Task<IntroduceYourselfReply> IntroduceYourself(IntroduceYourselfRequest request, ServerCallContext context)
        {
            if (string.IsNullOrEmpty(request.Name))
            {
                context.ResponseTrailers.Add(new Metadata.Entry("Name","the value was empty"));
                context.Status = new Status(StatusCode.InvalidArgument, $"Validation failed");
                return Task.FromResult(new IntroduceYourselfReply());
            }
            
            return Task.FromResult(new IntroduceYourselfReply
            {
                Name = request.Name,
                Job = "Developer",
                Country = "Canada",
                Citizenship = { new string[] {"France", "Canada" } },
                Skills = { new Skill[] { new Skill { SkillName = ".NET", SkillLevel = SkillLevel.Good }, 
                                         new Skill { SkillName = "CSS", SkillLevel = SkillLevel.Bad } } 
                }
            });
        }

context.ResponseTrailers is supposed to be filled, but clientSide the property trailers is empty.
Filling the status works fine by the way.

Is this a bug or I'am using ResponseTrailers not correctly?

This is a bug. Currently the .NET gRPC client doesn't populate trailers into RpcException.Trailers. This will be fixed in a future version.

GetTrailers() does return the trailers. What you can do for now with a unary method:

var call = client.IntroduceYourselfAsync(new IntroduceYourselfRequest());

try
{
    var response = await call;
}
catch (RpcException)
{
    // Log?
}

var trailers = call.GetTrailers();

Thank you!
