I have a multi-platform project with three modules: commonMain, jsMain, and jvmMain. The goal is to share data classes in commonMain so that my backend (in jvmMain) can serialize them to JSON and send them over the network using Ktor, which is working fine.
However, when trying to parse the JSON on the frontend (jsMain), I encounter an issue where I have to convert the parsed JSON into a dynamic type and then manually reconstruct the data class. This step is necessary to prevent the properties from being null.
This issue seems similar to https://discuss.kotlinlang.org/t/unable-to-read-properties-from-data-object-in-kotlin-js/26897/2

// Code that works
    window.fetch("<http://localhost:8080/>").then { response ->
           response.text()
       }.then { data ->
           val parsed = JSON.parse<Example>(data).asDynamic()
           val example = Example(parsed.i)
           println(example.i)
       }.catch {
           console.error(it)
       }

     // Code that fails
       window.fetch("<http://localhost:8080/>").then { response ->
           response.text()
       }.then { data ->
           val parsed = JSON.parse<Example>(data)
           println(parsed.i)
       }.catch {
           console.error(it)
       }


@Serializable
data class Example(val i: Int)

Because you're using JavaScript API to parse the response. Try with this Json.decodeFromString() method

I am trying to avoid having the serialization library on my frontend so I can have a smaller bundle size.

Then the dynamic approach needs to be followed

Is there no work around? I do not want to manually parse my types.
