getOrElse has the signature fun <B> TryOf<B>.getOrElse(default: (Throwable) -> B): B which means you must already have an Either inside the Try to have your code typecheck. Also Either<L, Nothing> indicates that it is always Left , which in your case makes sense because you always use the Left constructor and kotlin infers B to be Either<Error, Nothing> .
Instead of getOrElse , you should use toEither or fold .
