Hello guys, I am having a challenge with returning my response sealed class. I think is something to do with serialization but haven't been able to figure it out yet.

My error: Problem retrieving User.Try again later!
Serializer for class 'Success' is not found. Mark the class as @Serializable or provide the serializer explicitly.

Here is my sealed class.

@Serializable
sealed class Resource<T>(
    val data: T? = null,
    val message: String? = null,
    val token: String? = null
) {
    class Success<T>(data: T?, message: String, token: String? = null) :
        Resource<T>(data, message, token)

    class Error<T>(message: String, data: T? = null, token: String? = null) :
        Resource<T>(data, message, token)
}

You can rewrite your serializable classes in the following way to make it work:

@Serializable
sealed class Resource {
    @Serializable
    class Success<T>(val data: T, val token: String? = null) : Resource()

    @Serializable
    class Error(val message: String, val token: String? = null) : Resource()
}

@Serializable annotation is not inherited for subclasses/objects
