dotnet+MassTransit+RMQ issue while ussing IRequestClient<T> and NewtonsoftJson

Question

ASP.NET core API 6.0 + MassTransit 8.0.16 + Masstransit.Newtonsoft 8.0.16

I tried to implement request <-> response pattern and add newtonsoft serializer but faced with error after completing request. Not - Request and Response are successful and everything work fine. But finishing request there is an error in logs:

Repository which represent bug

If I remove:

cfg.ClearSerialization(); 
cfg.UseNewtonsoftRawJsonSerializer();

Everything works perfect but I need serializing for support another projects using rabbit mq and publish / consumer pattern.

I also tried:

cfg.ConfigureNewtonsoftJsonSerializer(s =>
{
    s.NullValueHandling = NullValueHandling.Ignore;
    return s;
});

Didn't help.

Answer 1

I got an answer on GitHub from the Author of MassTransit - Chris Patterson. Unfortunately, I can't use

cfg.ClearSerialization(); 
cfg.UseNewtonsoftRawJsonSerializer();

only

cfg.ClearSerialization(); 
cfg.UseNewtonsoftRawJsonSerializer(RawSerializerOptions.AddTransportHeaders | RawSerializerOptions.CopyHeaders);

with Request/Response Pattern

Ever with publish/consumer pattern, it works perfectly and the benefits were - that contract should follow all self namespace.
