Devise Omniauth callback error

Question

I have a web application running Devise and Omniauth to authenticate a user on Facebook. When I click on a link to log in though Facebook, it routes me to

/users/auth/facebook/callback?state=[state]code=[code]

Which is correct. But the page gives me the following error.

uninitialized constant ApplicationController::DeviseController

The line that it points to is in the ApplicationController

DeviseController.respond_to :html, :json

I've included my relevant code here https://gist.github.com/testrecord/5050992 In addition, I do have it set up in the initializer.

Has anyone seen an error like this? Any help is appreciated.
