    assert(
      'You attempted to use the <LinkTo> component within a routeless engine, this is not supported. ' +
        'If you are using the ember-engines addon, use the <LinkToExternal> component instead. ' +

  }
Method to assert that LinkTo is not used inside of a routeless engine. This method is
overridden in ember-engines link-to-external component to just be a noop, since the
link-to-external component extends the link-to component.
