OneOf Post Body

[Quip1995]

I'm trying to implement a oneOf POST route, but I'm getting an error indicating that:

"json: cannot unmarshal object into Go value of type MyInterface"

So far my only way to bypass this has been to declare an any type and then unmarshall the body myself, but that seems counter productive since I went through the effort of providing a Discriminator and the validation that huma provides appears to be working correct.

Obviously I can switch on the discriminator field myself and unmarhsall into the correct type, but it just feels like I'm doing something wrong here (perhaps many things wrong).

Apologies if this ends up being trivial, this is my first route with Huma.

Here is my setup:

       reg := router.OpenAPI().Components.Schemas

	// Register the schemas
	schemaOne := reg.Schema(reflect.TypeOf(concreteTypeOne{}), true, "concreteTypeOne")
	schemaTwo := reg.Schema(reflect.TypeOf(concreteTypeTwo), true, "concreteTypeTwo")

	// Create a oneOf schema that references the registered schemas
	oneOfSchema := &huma.Schema{
		Type: "object",
		OneOf: []*huma.Schema{
			reg.SchemaFromRef(schemaOne.Ref),
			reg.SchemaFromRef(schemaTwo.Ref),
		},
		Discriminator: &huma.Discriminator{
			PropertyName: "type",
			Mapping: map[string]string{
				"001": schemaOne.Ref,
				"004": schemaTwo.Ref,
			},
		},
	}

	op := huma.Operation{
		Method:      http.MethodPost,
		Path:        path,
		RequestBody: &huma.RequestBody{
			Required:    true,
			Content: map[string]*huma.MediaType{
				"application/json": {Schema: oneOfSchema},
			},
		},
	}

	huma.Register(router, op, func(ctx context.Context, input *struct {
		Body   myInterface
	}) (*struct{}, error) {
           fmt.Println("Did I make it?") 

	})

Again, the handler never executes and "Did I make it?" is never printed. It works great if I change Body to any, but it seems slightly self defeating.

Thanks for the help!
