Detekt: UseCheckOrError in conjunction with when statement

[vanniktech]

I don't know why detekt 1.0.0 flags the following with the UseCheckOrError rule:

fun zoneactionModelDir() = when (this) {
  IN -> ZoneactionModel.Dir.IN
  OUT -> ZoneactionModel.Dir.OUT
  else -> throw IllegalStateException("Are you lost?")
}

How should I rewrite this one?

I think I can assist.

fun zoneactionModelDir() = when (this) {
  IN -> ZoneactionModel.Dir.IN
  OUT -> ZoneactionModel.Dir.OUT
  else -> error("Are you lost?")
}
