request.env['omniauth.auth'] is nil in Ruby on Rails

Question

I trying export my data from rails app into google calendar, but after logging i cannot found 'omniauth.auth' into request.env.

I use Rails 4.0.4 and Ruby 2.0.0p481

My Gemfile

gem 'google-api-client', '~> 0.7.1', :require => 'google/api_client'
gem 'omniauth', '~> 1.2.1'
gem 'omniauth-google-oauth2', '~> 0.2.4'

omniauth.rb

OmniAuth.config.full_host = "http://localhost:3000"
Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2, 'MY_GOOGLE_CLIENT_ID', 'MY_GOOGLE_SECRET', { :access_type => 'offline', :prompt => 'consent', :approval_prompt => 'force', :scope => 'https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/calendar', :redirect_uri => 'http://localhost:3000/auth/google-oauth2/callback', }
end

controller

class GoogleAuthController < ApplicationController
  def create
    @auth = request.env['omniauth.auth'] #here not found 'omniath.auth' and @auth is nil

    if @auth.nil?
      flash[:danger] = "Error during connection with Google API."
      redirect_to holidays_path
    else
      @token = @auth['credential']['token']
      #another action after login
    end
  end
end

routes

match "/auth/:provider/callback", to: "google_auth#create", via: 'get'

Google apis (I cannot add a image, )

I'll be very grateful for help with this problem.

EDIT:

request.env

EDIT2:

OK. I localized problem. When i comment options in omniauth.rb it logged me

{ :access_type => 'offline', :prompt => 'consent', :approval_prompt => 'force', :scope => 'https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/calendar', :redirect_uri => 'http://localhost:3000/auth/google-oauth2/callback', }

Answer 1

Looking at the request.env hash, there is no omniauth.auth key - there IS an omniauth.state key...maybe that's what you want?

The end of the env hash also includes this:

unsigned_session_cookie"=>{
  "session_id"=>"465d10f227d1b1033088b17f3aa77cb3",
  "_csrf_token"=>"SghTPesnhyoSKhA2yFhM4d20/KjqIPixcFUSCpn5jX4=", 
  "omniauth.params"=>{},
  "omniauth.state"=>"fc29151421330cb904b4c4984bdd52e21a53d98531389b74", 
  "flash"=>{
    "discard"=>[:danger], 
    "flashes"=>{:danger=>"Error during connection with Google API."}}
  }
}

It could just be a problem with connection, as that flash message seems to suggest.
