Hi! I'm trying to use this to serialize messages to JSON -- I have a bunch of polymorphic definitions (see here: https://gist.github.com/jdkula/781c0edf83943df5e6dc9293f487029e) but I'm getting this error: java.lang.IllegalArgumentException: Can't locate polymorphic serializer definition (full stack trace: https://gist.github.com/jdkula/511b45a5de8224775418a39c23199d84)

I'm compiling to Javascript from a common module. I'm using Kotlin 1.2.30.

Is that your case? https://github.com/Kotlin/kotlinx.serialization/issues/88#issuecomment-367249678

I don't think so -- I'm not using a map, nor any other type with generics.

Does it help if you remove @Serializable from the base classes?

What I did in a somewhat similar situation was to have a custom serializer on the super class which decides which sub class to serialize to, and just remove @Serializable on the sub classes. In the custom serializer I used input.read(Data::class.serializer()) where Data is a data class with all possible fields

Interesting... I'll try that. Thanks!
