Hi, I'm following the Udacity bootcamp and one of the examples in the lecture doesn't work for me, this is the code:

package aquarium

class Aquarium (var length: Int, var width: Int, var height: Int) {

    var volume: Int
        get() = width * height * length / 1000
        set(value) = {height = (value * 1000) / (width * length)}

This is the warning I'm getting from Intellij for the set(value):

Type mismatch: inferred type is () -> Unit but Unit was expected

I don't understand what is this supposed to signify?

You need to remove the = after set(value)

You need to remove the the = in set(value) = { ... } otherwise you are indicating that the setter is returning a lambda. The Type mismatch: inferred type is () -> Unit but Unit was expected is indicating that by stating that the compiler is expecting a Unit type but is finding () -> Unit as type. Remember that a { starts a block and that } ends a block, and assigning a block is creating a lambda. I make that mistake a lot too, even after working with kotlin for years. 😅
