As commented by AlexTa you're getting a TypeCastException because you cast null to a non-null type.

In Kotlin types are "@NotNull" by default. So if you declare a variable like this:

var yourVar: String

you cannot assign null to it. If it should be capable of storing null (which it often shouldn't) you declare it like this:

var yourVar: String? = null
