Hi!

I have the current code:

@Serializable
private data class ApiUsernamePassword(val username: String, val password: String)

I use Ktor (it handles serialization itself). On Kotlin/JVM, the code runs fine, but on Kotlin/JS I get:

SerializationException: Can't locate argument-less serializer for class ApiUsernamePassword. For generic classes, such as lists, please provide serializer explicitly.
	at <global>.serializer([REDACTED]/runtime/commonMain/src/kotlinx/serialization/PlatformUtils.kt:12)

I use version 0.14.0 of the serialization plugin, with Kotlin 1.3.61 and Gradle 6.0.1

You need Kotlin 1.3.60 for runtime 0.14.0

Ktor says they don't support it though...

Nevermind, I have Kotlin 1.3.61

Magic private modifier?
