Hi guys, I’m using ktor+kotlinx.serialization. When I’m trying to get typed response I get a runtime crash:

Exception in thread "main" java.lang.NoClassDefFoundError: kotlinx/serialization/ShorthandsKt

at io.ktor.client.features.json.serializer.KotlinxSerializerKt.buildSerializer(KotlinxSerializer.kt:91)

Can you point me what’s wrong? ktor 1.3.1, serialization 0.20.0

Ktor 1.3.1 should use serialization 0.14.0 and Kotlin 1.3.61.

Thanks, it helped. I didn’t know that switching to the latest version of kotlin and serializable plugin can break the build 😀

Only until we get a new version of ktor. 🤞 we get a new one soon.
