Sealed classes cannot be deserialised on JS side with new IR compiler

[zypus]

I just tried upgrading my fullstack (ktor) project to kvision 4.0.0, however I ran into issues with the IR compiler. Apparently kotlinx.serialization 1.0.0 does not yet support finding the serializer for sealed classes: https://github.com/Kotlin/kotlinx.serialization/issues/1116

ie. something like this in the common module:

@Serializable
sealed class FirmwareLogResponse {
    @Serializable
    object Clear: FirmwareLogResponse()
    @Serializable
    data class InitLog(val logLines: List<LogLine>): FirmwareLogResponse()
    @Serializable
    data class UpdateLog(val logLine: LogLine): FirmwareLogResponse()
    @Serializable
    object LogHeartBeat: FirmwareLogResponse()
}

So this is no direct issue of kvision, but I put this here to be aware of this issue.

It works fine when I use the legacy compiler on the js side.

kotlin.js.compiler=legacy

Thanks for the information!
I've added this note to KVision documentation as well.

Thanks I have seen the entry.
Might be worth mentioning in the migration guide as well.

Should be fixed now
