I tried to create an initializer with:

Rails.application.configure do
  config.view_component.generate ||= ActiveSupport::OrderedOptions.new(false)
  config.view_component.generate.stimulus_controller = true
  config.view_component.generate.locale = true
  config.view_component.generate.distinct_locale_files = true
  config.view_component.generate.preview = true
end

And discovered that :view_component_path is also nil. After also adding config.view_component.view_component_path = "app/components" to my configuration I was able to run the generator successfully.

@Spone, is this a good workaround?
