Hide sidebar and navbar in some states

I'm using the code below to hide the navbar and sidebar in my application template in the routes: index.index, login.index, errors.404, errors.505 and errors.feature:

  hideNavbarAndSidebar: computed.equal('currentRouteName',
    'index.index',
    'login.index',
    'errors.404',
    'errors.505',
    'errors.feature'
  ),

The problem is: Doesn't work. Will only work in the first route, the index.index

How could i improve this code to make what i need??

Thanks.
