I’m trying to use OmniAuth in a sinatra app with google as the login provider. Using the twitter and facebook providers work fine:

require 'omniauth'
require 'openid'
require 'openid/store/filesystem'


use OmniAuth::Builder do
use OmniAuth::Strategies::OpenID, OpenID::Store::Filesystem.new('./tmp'), :name => 'google', :identifier => 'https://www.google.com/accounts/o8/id'  
end

get '/sign_in'
  redirect '/auth/google'
end

Thoughts? When the browser tries to get ‘/auth/google’, it gets a 503 – Service Unavailable. There is nothing in the heroku logs

Thoughts or suggestions on what this might be?

I just started a bounty on this question – what I’m hoping for is a sample implementation that works on heroku.

I increased the log level on heroku. Here is what I’m getting now:
