kotlinx.serialization.json.internal.JsonDecodingException: Serializer for subclass 'admin.sign_up' is not found in the polymorphic scope of 'NetworkNotification'.
Check if class with serial name 'admin.sign_up' exists and serializer is registered in a corresponding SerializersModule.
To be registered automatically, class 'admin.sign_up' has to be '@Serializable', and the base class 'NetworkNotification' has to be sealed and '@Serializable'.
