Hello, how could I solve this generic parameter issue?

@Serializable(ASerializer::class)
sealed class A

@Serializable
class B<T : A> : A()

object ASerializer : KSerializer<A> {
    @OptIn(ExperimentalSerializationApi::class, InternalSerializationApi::class)
    override val descriptor: SerialDescriptor = buildSerialDescriptor(
        serialName = "A",
        kind = PolymorphicKind.SEALED
    ) {
        element(
            elementName = "B",
            descriptor = /* ... */ // What should I pass in here?
        )
    }

    override fun serialize(encoder: Encoder, value: A) {
        TODO("Not yet implemented")
    }

    override fun deserialize(decoder: Decoder): A {
        TODO("Not yet implemented")
    }
}

since T doesn't seem to be used,

descriptor = B.serializer(NothingSerializer()).descriptor

would probably work in this minimal example

[ephemient]

if you really use T, then what you pass in to B.serializer(KSerializer<T>) will have to change

Thank you, T is used in primary properties. I just omitted them. If so, could you explain a bit more? I kinda don't get your "will have to change".
