Namespacing Config Fails Out of the Box

[brchristian]

I created a brand new Rails (6.0.3.3) app and added Deface to the Gemfile. I ran bundle.

Then, following the README, I went into config/application.rb and added the following:

config.deface.namespaced = true

When I try to run my Rails app, it crashes instantly, with:

ruby/2.6.6/gems/railties-6.0.3.3/lib/rails/railtie/configuration.rb:96:in `method_missing’:
undefined method `deface' for #<Rails::Application::Configuration:0x00007ffae8262448> (NoMethodError)
        from fooapp/config/application.rb:19:in `<class:Application>'

What am I doing wrong?
