# serialization

I'm trying to use generics in a custom serializer like this

@Serializable
data class Tab<T>(
  @Serializable(ContentSerializer::class)
  val content: T? = null
) {
  private class ContentSerializer<T : Any>(tSerializer: KSerializer<T>) : JsonTransformingSerializer<T>(tSerializer) {
    override fun transformDeserialize(element: JsonElement) = element.jsonObject.values.last()
  }
}

But android studio show

Class 'ApiBrowse.Contents.BrowseResultsRenderer.Tab.ContentSerializer<*>', which is serializer for type 'Any', is applied here to type 'T?'. This may lead to errors or incorrect behavior.

And i get some cursed internal backend compilation error

This is maybe silly, but should ContentSerializer apply to type Any? and not Any?

I don't think Any can be marked nullable

same error without nullable T
