Hi all! I have a Kotlin-based frontend project using React, and now I want to extract DTOs to a multiplatform Gradle module. The problem is that now in runtime, I'm getting: Uncaught TypeError: e.defineModule is not a function. When looking into my bundle, e.defineModule occurs only once in such context:

e.defineModule("kotlinx-serialization-kotlinx-serialization-core-jsLegacy",t)

Indeed I want to use kotlinx.serialization. This happens on legacy JS backend, and on IR some misterious ClassCastException occurs at runtime (maybe more changes would be required to make the project work with IR).

let me know if I should prepare a minimal reproducer

solved - I updated org.jetbrains.kotlinx:kotlinx-serialization-json from 1.0.0 (pretty old) to 1.3.0
