How do I make this polymorphically serializable?

@Serializable
sealed class Result<T> {
    @Serializable
    class Success<T>(val data: T) : Result<T>()

    @Serializable
    class Failure<T>(val msg: String) : Result<T>()
}

So that If I have a class

@Serializable
data class Person(val name:String)

I can call

Json.stringify(Result.Serializer(Person.serializer()),Result.Success(Person("Andy)))

I have little knowledge in Polymorphic Serialization

It's been a while, but that seems correct. I would assume that that would work in 2 directions?

[andylamax]

It doesn't work. Says Person is not registered for Polymorphic Serialization

[Kroppeb]

Huh, I don't understand why it's saying that.

I cannot get it working too, I only can stringify if I get the result success data, but stringify the result is giving me the same errors, even trying adding multiple @Polymorphic annotations to the properties

[andylamax]

Same here . . .

The sealed class is working perfectly with Jake Wharton serializer and a custom adapter for retrofit, maybe there you can see some hint

Can I get a link?
