Issues with DocumentJsonSerializerOptions serialization and derived types

[giannik]

I'm having some issues lately with Serialization of derived C# types using DocumentJsonSerializerOptions .

In Orchard Core you can define the derived types for serialization from this serviceL

  services.AddJsonDerivedTypeInfo<derived, base>();

But I noticed lately (this was not happening about a month ago )that when you try to serialize the derived type that has been defined from the startup services that when you serialize it doesn't contain the type info metadata to later on deserialize it back to the derived type.
As an example the following code serializes the ContentDeploymentStep without the type info metadata :

public class TestController : Controller
  private readonly JsonSerializerOptions _jsonSerializerOptions;
 public TestController (
        IOptions<DocumentJsonSerializerOptions> jsonSerializerOptions
  )
{
   _jsonSerializerOptions = jsonSerializerOptions.Value.SerializerOptions;
}
  public Task<IActionResult> Test()
    {
         var TestDerivedType= new ContentDeploymentStep(){Name = "Test"};
         var serialized= JsonSerializer.Serialize(TestDerivedType, _jsonSerializerOptions); //serialized string does not contain the type information 
           metadata
    }

     
  //later on when deserializing back it does not convert to the derived class but to base class

Can someone please confirm if it happens on their side?
