How to mock sealed classes with mockk?

Question

I am trying to mock a sealed class which looks something like this:

sealed class Location

class Home: Location{
    val name = "Home"
}

I would like to be able to do the following:

val mockHome = mockk<Home>() {
    every { name } answers { "My Home" }
}

But unfortunately when I run this it fails with the following error:

io.mockk.MockKException: Missing calls inside every {... } block.

What am I doing wrong?
