Polymorphic SerializersModule with generic class "Star projections in type arguments are not allowed"

Consider this code:

val responseModule = SerializersModule {
    polymorphic(Response::class) {
        subclass(OkResponse::class)
    }
}

@Serializable
abstract class Response<out T>
            
@Serializable
class OkResponse<out T>(val data: T) : Response<T>()

Running it produces:

Caused by: java.lang.IllegalArgumentException: Star projections in type arguments are not allowed, but had example.examplePoly17.OkResponse<*> (Kotlin reflection is not available)

Not sure this is related, but I had the same error.

I found the following workaround: in my case, there was an interface constraint on the generic, and I could register the subclass as follows causing the error to disappear:

subclass(
    OkResponse::class,
    OkResponse.serializer( PolymorphicSerializer( InterfaceConstraint::class ) )
        as KSerializer<OkResponse<*>>
)
