Hi, is there a way for me to serialize a property named type with polymorphic serialization ? I already changed classDiscriminator to __type__ but the property is still not serialized, even when setting a custom SerialName or JsonNames on the property, it still get skipped.

Here is an example code :

@Serializable
sealed interface RecipeType {
    abstract val type: MyEnum
}

@Serializable
data class Blasting(var result: String) : RecipeType {
    override val type = MyEnum.BLASTING
}

@Serializable
data class Crafting(var result: String) : RecipeType {
    override val type = MyEnum.CRAFTING
}

I found what was the problem, it's because of encodeDefaults setting. When it's turned off, as I set a default value for type property in my subclasses, it will skip it.
So the solution is either using @EncodeDefault on the type property of each subclasses, or changing the encodeDefaults setting, but it could introduce some problems. If anyone has a similar problem I encourage you to also set explicitNulls to false to avoid some nulls being serialized even when encodeDefaults is true.
