I am trying to get custom serializing to work with kotlinx.serialization like this reduced example:
@Serializable
open class KdfParams {
var dklen: Int = 0
var salt: String? = null
@Serializer(forClass = KdfParams::class)
companion object {
override fun save(output: KOutput, obj: KdfParams) = TODO()
override fun load(input: KInput): KdfParams {
return KdfParams()
}
}
}
but I get:
java.lang.IllegalArgumentException: JSON at 369: Expected '[, kind: POLYMORPHIC'
