Circular dependency detected while autoloading constant Api

[joannatdl]

I'm using this gem together with the module ng-token-auth in my Ionic mobile app (which bases on angular).
After logging in, if I reload the page, a request auth/validate_token will be sent. I get a 'Circular dependency detected while autoloading constant Api' on that.
I'm also using the gem grape for building the API, which could also be the source of the problem.

This is my routes.rb file (devise is also included because I'm using it in my Rails app which contains the API):

Rails.application.routes.draw do
  devise_for :users, controllers: { omniauth_callbacks: 'omniauth_callbacks'}
  namespace :api do
    mount_devise_token_auth_for 'User', at: '/v1/auth'
    mount API => '/'
    mount GrapeSwaggerRails::Engine => '/doc'
  end
  (...)
end

There is no useful info in the server logs. How can I solve this problem?
Thank you!

Can you try upgrading to version 0.1.31.beta8? This looks like it may be related to an issue with namespace that was just fixed in that version.
