      null shouldn't be returned by a Scala library. None should be returned instead. So, Observable.head could be changed to this:

      // Some comments here
  def head(): Future[T] = {
    headOption().map {
      case Some(result) => result
      case None         => None.asInstanceOf[T] 
    }(Helpers.DirectExecutionContext)
  }
