The package name is changed,..getting exception in kotlinx.serialization 1.0.0-RC

Serializer for class 'e' is not found.
    Mark the class as @Serializable or provide the serializer explicitly.

Data classes are in shared code. Why progaurd configuration is not working with minify enabled. can anyone help what I am missing here?

May be worth posting in #serialization

Okay, thanks
