How to setup JsonApiSerializer as default input and output seriliazers C# .NET Core 3+

I've been trying to setup JsonApiSerializer (https://github.com/codecutout/JsonApiSerializer) as the default serializer for both input and output so I can have an json:api compliant .NET server for an Ember application with Ember Data.

I have succesfully setup the output serializer by writing the following code to the Startup.cs file:

public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllers();
            services.AddDbContext<Context>(options => options.UseSqlServer(Configuration.GetConnectionString("myDb")));

            var sp = services.BuildServiceProvider();
            var logger = sp.GetService<ILoggerFactory>();
            var objectPoolProvider = sp.GetService<ObjectPoolProvider>();

            services.AddMvc(opt =>
            {
                var serializerSettings = new JsonApiSerializerSettings();
**
                var jsonApiFormatter = new NewtonsoftJsonOutputFormatter(serializerSettings, ArrayPool<Char>.Shared, opt);
                opt.OutputFormatters.RemoveType<NewtonsoftJsonOutputFormatter>();
                opt.OutputFormatters.Insert(0, jsonApiFormatter);
**
                var mvcNewtonsoftSettings = new MvcNewtonsoftJsonOptions();

                var jsonApiInputFormatter = new NewtonsoftJsonInputFormatter(logger.CreateLogger<NewtonsoftJsonInputFormatter>(), serializerSettings, ArrayPool<Char>.Shared, objectPoolProvider, opt, mvcNewtonsoftSettings);
                opt.InputFormatters.RemoveType<NewtonsoftJsonInputFormatter>();
                opt.InputFormatters.Insert(0, jsonApiInputFormatter);
                //opt.InputFormatters.OfType<NewtonsoftJsonInputFormatter>().FirstOrDefault().SupportedMediaTypes.Add("application/vnd.api+json");

            }).AddNewtonsoftJson();
        }

But the Input part isn't working yet!

I've been triyng to receive code from a Ember application that follows this structure:

{
  "data": 
  {
    "type": "manufacturer",
    "name": "Fabricante 1",
    "relationships": {
      "products": {
        "data": [
          {
            "type": "product",
            "id": "1"
          },
          {
            "type": "product",
            "id": "2"
          }
        ]
      }
    }
  }
}

The binding model of the .NET server for POSTing a manufacturer is like this:

public class CreateManufacturerBindingModel
    {
        public string Type { get; set; } = "manufacturer";
        public string Name { get; set; }
        public AssignProductBidingModel[] Products { get; set; }
    }

public class AssignProductBidingModel
    {
        public string Type { get; set; } = "product";
        public int Id { get; set; }
    }

I've been trying out some variations of those codes for a while and all I can get is Null values for "Name" and "Products" attributes of the CreateManufacturerBindingModel

Does anyone has any clue of why I keep on getting null values at the .NET server?

Thank you for your attention!
