IOError not opened for reading about rails_panel HOT 9 CLOSED

While #52 says that 0.2.5 should improve Rails 4 pre-release support, I am still seeing the above issue with this newer meta_request version and Rails 4.0 RC1. Perhaps one of my other dependencies is causing the conflict instead.

Can you please paste your Gemfile. Thanks.

This is ultra low-priority for me, I'm only a hobby programmer experimenting with bumping a project app to Rails 4. I appreciate you taking the time to look at it whenever you like.

Not sure if this will help, but quick research into this error shows that app_request.events contains 'process_action.action_controller' event which references (via payload[:request]) the current Rack::Request. Calling to_json on Rack::Request object fails for me, probably because it contains references to IO objects (like STDERR). Tested on ruby 2.0, Rails 4 RC1.

@shanesveller thank you very much for the Gemfile. It helped me recreate the issue and fix it. The newrelic_rpm gem set the payload[:request] that contained some closed IO as @zzemia discovered.

Fix is in meta_request 0.2.6.

Works for me. Thanks!
