Hello, big congratz to the Kotlin JS Team for 1.4-M1 👏👏👏👏
I’ve tried it right now and @JsExport has an issue with a data class that is @Serializable :

@CommonJsExport
@Serializable
data class EventDetails(var answer_id: Int? = null)

At compilation, I get the following error:

e: java.lang.AssertionError: Properties without fields are not supported my.package.EventDetails.Companion_instance

So the generated serializer() of kotlinx-serialization blocks @JsExport

Hi! Can you create an issue here - http://kotl.in/issue and attach sample code

Hi, sure will do 🙂

This happens for every class with a companion object, not related to serialization.

Indeed, thank you @diesieben07
