I have a custom exception e.g.

expect open class FirebaseException(message: String) : Exception

And in Android actual code:

import com.google.firebase.FirebaseException

actual typealias FirebaseException = FirebaseException

In the commonMain code, I have a sub-class of this

class DocNotFoundException : FirebaseException(
    "Fetched document is not present in the collection"
)

I have a Result class for backend communication and here it looks like:

sealed class Result<out R> {
    data class Success<out T>(val data: T) : Result<T>()
    data class Error(val ex: Exception) : Result<Nothing>()
}

In my ViewModel of Android module, when I use the above exception like this:

if (result is Result.Error && result.ex is DocNotFoundException) {
    // Do something
}

I get an error saying:

Incompatible types: DocNotFoundException and kotlin.Exception /* = java.lang.Exception */

NOTE: This is only in IDE (AS), when I compile the code, it works fine.
