@Serializable objects cause compilation errors

Hi when i run this code i get java.lang.NoSuchFieldError: Companion exception.

fun main() {
    val a = A // Throws java.lang.NoSuchFieldError: Companion
}

@Serializable
object A

@Serializer(forClass = A::class)
object ASerializer : KSerializer<A> {

    override val descriptor = SerialClassDescImpl("ASerializer")

    override fun serialize(encoder: Encoder, obj: A) = encoder.encodeString(obj::class.qualifiedName!!)

    override fun deserialize(decoder: Decoder): A = decoder.decodeString().run { A }
}

@Serializable object is supported starting from Kotlin 1.3.60/kotlinx.serialization 0.14.0

@pdvrieze I agree with what you are saying but this is a very early stage of the project so it will do for now. In the future I will have to change it to be more portable with a custom serializer for sealed class Error.
