Question

I am using omniauth-identity and configure its “fail on registration”.

My files:

config/initializers/omniauth.rb

OmniAuth.config.logger = Rails.logger

Rails.application.config.middleware.use OmniAuth::Builder do
  #...
  provider :identity, on_failed_registration: lambda { |env|
    IdentitiesController.action(:new).call(env)
  }
end

config/routes.rb

Wie::Application.routes.draw do
  root to: 'categories#index'

  ActiveAdmin.routes(self)
  devise_for :admin_users, ActiveAdmin::Devise.config

  match 'auth/:provider/callback', to: 'sessions#create'
  match 'auth/failure', to: 'sessions#failure'
  match 'signout', to: 'sessions#destroy', as: 'signout'
  resources :identities#, only: [:new]
  resources :categories, path: '', only: [:index] do
    resources :entries, path: '', only: [:index, :show]
  end
end

app/controllers/identities_controller.rb

class IdentitiesController < ApplicationController
  def new
    ariane.add "New Account"

    @identity = env['omniauth.identity']
  end
end

When I have a failure on registration (passing incorrect mail), I get the following:

in browser:

Routing Error

No route matches {} Try running rake routes for more information on
available routes.

in server log:

What can be the reason for this? What did I wrong?

UPDATE
What I do not understand is – why I get Started POST "/auth/identity/register"? According to omniauth configuration I should get the view correspondent to the IdentitiesController.action(:new), i.e. /identities/new …

The issue cannot be reproduced on the 1.1.0 version of omniauth-identiry. So update to latest version fixed the issue.
