How to fix Unmarshalling unknown type code XXX at offset YYY in Android?

Question

I\'m having app crash on resume because of Unmarshalling exception. I\'ve checked all the Serializables have constructor with no parameters and even checked all the serializ

Using Kotlin, the object 'Nota' has a Custom object 'CentroCusto' that contains only primitive properties.

class Nota(var id: Int? = null, var centroCusto: ArrayList? = null) : Parcelable {

constructor(source: Parcel) : this(
        source.readValue(Int::class.java.classLoader) as Int?,
        //Exception in below line -> Unmarshalling unknown type code 
        source.createTypedArrayList(CentroCusto.CREATOR) 
)

override fun describeContents() = 0

override fun writeToParcel(dest: Parcel, flags: Int) = with(dest) {
    writeValue(id)
    writeTypedList(centroCusto)
}

companion object {
    @JvmField
    val CREATOR: Parcelable.Creator = object : Parcelable.Creator {
        override fun createFromParcel(source: Parcel): Nota = Nota(source)
        override fun newArray(size: Int): Array = arrayOfNulls(size)
    }
}

The CentroCusto class:

class CentroCusto(var id: Int? = null, var descricao: String? = null, var aprovacaoDiretoria: Int? = null, var permiteMarcar: Boolean? = null) : Parcelable {

constructor(parcel: Parcel) : this(
        parcel.readValue(Int::class.java.classLoader) as? Int,
        parcel.readString(),
        parcel.readValue(Int::class.java.classLoader) as? Int,
        parcel.readValue(Boolean::class.java.classLoader) as? Boolean) {
}

override fun writeToParcel(parcel: Parcel, flags: Int) {
    parcel.writeValue(id)
    parcel.writeString(descricao)
    parcel.writeValue(aprovacaoDiretoria)
    parcel.writeValue(permiteMarcar)
}

override fun describeContents(): Int {
    return 0
}

companion object CREATOR : Parcelable.Creator {
    override fun createFromParcel(parcel: Parcel): CentroCusto {
        return CentroCusto(parcel)
    }

    override fun newArray(size: Int): Array {
        return arrayOfNulls(size)
    }
}

}
