title: checkout in spree3 application on heroku not working, can't find error in logs
body: <p>I am having trouble in my heroku deployment of a spree3 application. Whenever I click the checkout button I am getting an error. I configured the application to use the Stripe Gateway on the Admin Payments Section.</p>
  
  <p>I have spent all day looking for an answer but I haven't been able to find anything. Checkout works in development but not in production. </p>
  
  <p>Also, everything else seems to work in production environment except checkout.  </p>
  
  <p>This is my Gemfile:</p>
  
  <pre><code>source 'https://rubygems.org'
