Hello,
I have a sealed class with a companion object that has some fields and functions that access fields in the declared object and inner sealed class.

In JVM it compiles fine, but in KotlinJS it says that it cannot resolve the fields.
In this example the Error Unresolved reference 'name' would be at the it.name

sealed class Product(open val name: String) {
    object TestProduct1 : Product("Test1")

    sealed class MetaProduct(override val name): Product(name) {
        object SubProduct1: MetaProduct("sub1")
        object SubProduct2: MetaProduct("sub2")
    }

    companion object {
        val entries = listOf(
            TestProduct1,
            MetaProduct.SubProduct1,
            MetaProduct.SubProduct2
        )
        val byName = entries.associateBy { it.name } // Error here in KotlinJS, but not JVM
    }
}

I have the solution, I just needed to specify the type on the listOf to listOf<Product>
