Hey everyone, I have the following response classes. Check this to get some more context about why I have structured it as below.

@Serializable
sealed interface PaginatedItems

@Serializable
data class GetPaginatedResponse(
    val isNext: Boolean,
    val content: PaginatedItems
)

@Serializable
data class TracksPage(
    val items: List<TrackInfo>
) : PaginatedItems

Now, when I hit my endpoint I get the following json

{
  "isNext": false,
  "content": {
    "type": "io.github.rubenquadros.vibesync.server.model.MediaPage",
    "items": []
  }
}

I don't understand how this type param is getting added in the json

that's the discriminator, KxS adds it automatically when encoding polymorphic types https://github.com/Kotlin/kotlinx.serialization/blob/v1.6.3/docs/polymorphism.md#sealed-classes
