With new backend IR, should kotlinx serialization library be updated to specific version? Getting this crash when run build with IR enabled (Kotlin 1.4.31, Kotlinx serialization 1.0.1)
Copy code

Fwiw I use serialization gradle plugin 
org.jetbrains.kotlin:kotlin-serialization:1.5.0-M2
and library 
1.1.0
and it doesn’t crash for me
i
going to try, thx for the tip
nope, still crashing for me
r
That’s the issue you’re looking for https://youtrack.jetbrains.com/issue/KT-44779
i
yes that exact issue, thx 😞
l
Doesn't that happen when the 
enum class
lacks the 
@Serializable
annotation?
In the current/legacy JVM, it doesn't fail, but the JVM IR seems stricter (though doesn't always pinpoint to the actual root cause, which is understandable when compiler plugins are involved)
