can't convert Pathname into String when using Facebook api in Rails

we are trying to build a facebook app using ruby on rails. We setup a canvas app and are able to see our app through the canvas, but when we try to integrate the ruby facebook api we get a 'can't convert Pathname into String' error whenever we try to make a request for user data. We have tried 2 different api's so far (koala and rest-graph) and had the same result. I even downloaded a working project from koala api sample project and got the same error. I'm not sure if it is a rails error or because we are trying to run this using rails s localhost:3000 I had a previous ssl error and had to add this code under config/initializers to fix that ``` require 'open-uri' require 'net/https' module Net class HTTP alias_method :original_use_ssl=, :use_ssl= def use_ssl=(flag) self.ca_file = Rails.root.join('lib/ca-bundle.crt') self.verify_mode = OpenSSL::SSL::VERIFY_PEER self.original_use_ssl = flag end end end ```
