OAuth2::Error in callback2 when trying to connect consumer to facebook

Using rails 4 and the following gems: oauth (0.4.7) oauth-plugin (0.5.1) oauth2 (0.9.4)

I changed the OauthConsumersController class to have the following to get the exception.

def callback2
    begin
      super
    rescue Exception => e 
      puts e.response.inspect
      puts e.code.inspect
      puts e.description.inspect
    end
end

and the value of e.response is:

#<OAuth2::Response:0x007fea70c65ae0 @response=#<Faraday::Response:0x007fea70c5ec68 @on_complete_callbacks=[], @env=#<Faraday::Env @method=:post @body="access_token=token_removed_for_security_reasons&expires=5145879" @url=#<URI::HTTPS:0x007fea70fbe660 URL:https://graph.facebook.com/oauth/access_token> @request=#<Faraday::RequestOptions (empty)> @request_headers={"User-Agent"=>"Faraday v0.9.0", "Content-Type"=>"application/x-www-form-urlencoded"} @ssl=#<Faraday::SSLOptions verify=true> @response_headers={"content-type"=>"text/plain; charset=UTF-8", "pragma"=>"no-cache", "access-control-allow-origin"=>"*", "x-fb-rev"=>"1306262", "cache-control"=>"private, no-cache, no-store, must-revalidate", "expires"=>"Sat, 01 Jan 2000 00:00:00 GMT", "x-fb-debug"=>"BaE/kxwDArTbj7L/f6QFrklMuuOnUsoIPt0N1LpMbs+4+V4tP+QkkupCzZhMyUYmo1mhfpVimzzJ1+dQ1cxVrg==", "date"=>"Thu, 26 Jun 2014 12:25:54 GMT", "connection"=>"close", "content-length"=>"211"} @status=200>>, @options={:parse=>nil}, @error=#<OAuth2::Error: access_token=token_removed_for_security_reasons&expires=5145879>, @parsed="access_token=token_removed_for_security_reasons&expires=5145879">

and my oauth_consumers.rb is:

OAUTH_CREDENTIALS={
   :facebook=>{
     :key => APP_CONFIG['facebook_consumer_key'],
     :secret => APP_CONFIG['facebook_consumer_secret'],
     :oauth_version => 2,
     :super_class => 'Oauth2Token',
     :scope => 'offline_access,publish_stream',
     :options => {
       :site => 'https://graph.facebook.com',
       :scope => 'offline_access,publish_stream',
       :token_url => '/oauth/access_token',
       :redirect_uri => 'http://0.0.0.0:3000/oauth_consumers/facebook/callback2'
     } 
   }
}

OAUTH_CREDENTIALS={
} unless defined? OAUTH_CREDENTIALS

load 'oauth/models/consumers/service_loader.rb'

i added the token_url and redirect_url because of errors I received from the gem and facebook.

Any ideas why this is happening?
