Challenge 1 / 2

Check out the following config:

netgen_layouts:
    view:
        item_view:
            app:
                recipes_app:
                    template: 'nglayouts/admin/recipe_item.html.twig'
                    match:
                        item\value_type: 'doctrine_recipe'

What would happen if we changed app: to foobar:?

No error, but this template would no longer be used in the admin area.

An error! foobar is not a valid key here.

Nothing - that key is meaningless.
