            }

}

Why is the code in this submodule saying serialization and datetime don't exist when I try to compile it, but only for compileKotlinJs?

Looks like it’s a reported issue https://github.com/Kotlin/kotlinx.serialization/issues/1365

Mine is not using inner classes though

[martmists]

@Serializable
data class CommentObject(
    val id: Long,
    val post: Long,
    val parent: Long?,
    val author: Long,
    val content: String,
    val created: LocalDateTime,
    val updated: LocalDateTime
)

Can you try cleaning and rebuilding the project?

[martmists]

The same error occurs

[Mayank]

Can you share a sample project to reproduce the issue? I can try to build on my machine and see if I can find the cause
