A new user recently attempted to use my app and generated the following error: A Facebooker::Session::MissingOrInvalidParameter occurred in home#index: Invalid parameter [RAILS_ROOT]/vendor/plugins/facebooker/lib/facebooker/parser.rb:487:in `process'' This appears to have happened when facebooker attempted to parse the response of facebook.auth.getSession. I have never seen anything fail in this area, so I''m eager to write this off as a temporary facebook quirk, but I don''t see anyone else reporting problems on the developer forums. Is anyone else seeing this problem? The failure was in this method: def self.process(data) response_element = element(''error_response'', data) rescue nil if response_element hash = hashinate(response_element) exception = EXCEPTIONS[Integer(hash[''error_code''])] || StandardError raise exception.new(hash[''error_msg'']) #### line 487 end end Here are the request parameters and the backtrace: ------------------------------- Request: ------------------------------- * URL : http://**. inigral.com/?auth_token=34a2311df88b8a1f3a847064e7450407&installed=1 * IP address: 69.63.176.230 * Parameters: {"format"=>"fbml", "fb_sig_time"=>"1229116842.827", "fb_sig"=>"b720e5366299ba47e676874d4be4457c", "fb_sig_in_new_facebook"=>"1", "_method"=>"GET", "fb_sig_locale"=>"en_US", "installed"=>"1", "action"=>"index", "fb_sig_position_fix"=>"1", "fb_sig_in_canvas"=>"1", "fb_sig_request_method"=>"GET", "auth_token"=>"34a2311df88b8a1f3a847064e7450407", "controller"=>"home", "fb_sig_added"=>"0", "fb_sig_api_key"=>"4ea2871be8fb71d66673d3692d94c6bc"} ------------------------------- Backtrace: ------------------------------- [RAILS_ROOT]/vendor/plugins/facebooker/lib/facebooker/parser.rb:487:in `process'' [RAILS_ROOT]/vendor/plugins/facebooker/lib/facebooker/parser.rb:15:in `parse_without_logging'' [RAILS_ROOT]/lib/facebooker_extensions.rb:18:in `parse'' [RAILS_ROOT]/vendor/plugins/facebooker/lib/facebooker/service.rb:14:in `post_without_api_logging'' [RAILS_ROOT]/lib/facebooker_extensions.rb:7:in `post'' [RAILS_ROOT]/vendor/plugins/facebooker/lib/facebooker/session.rb:485:in `post_without_logging'' [RAILS_ROOT]/vendor/plugins/facebooker/lib/facebooker/session.rb:496:in `post'' [RAILS_ROOT]/vendor/plugins/facebooker/lib/facebooker/logging.rb:17:in `log_fb_api'' /usr/lib/ruby/gems/1.8/gems/activesupport-2.1.0/lib/active_support/core_ext/benchmark.rb:8:in `realtime'' [RAILS_ROOT]/vendor/plugins/facebooker/lib/facebooker/logging.rb:17:in `log_fb_api'' [RAILS_ROOT]/vendor/plugins/facebooker/lib/facebooker/session.rb:495:in `post'' [RAILS_ROOT]/vendor/plugins/facebooker/lib/facebooker/session.rb:155:in `secure!''
