Join them; it only takes a minute: Sign up Heroku 500 Internal Server Error up vote 3 down vote favorite I am developing a Ruby on Rails app and attempting to deploy it with Heroku however I have some errors heroku error logs that I cannot solve. I have gone through the Heroku log and can see the details but I don't know what is wrong. The problem appears to me to be coming from my _header.html.erb file but I don't know why. Any help would be appreciated thanks.

Heroku Debug 500 Error
them; it only takes a minute: Sign up Debugging heroku 500 server error? up vote 3 down vote favorite 2 So this is what I get from looking at my production.logs from heroku: Completed 200 OK in 63ms (Views: http://stackoverflow.com/questions/9017668/heroku-500-internal-server-error 6.0ms | ActiveRecord: 50.3ms) Processing by EventsController#show as HTML Parameters: {"id"=>"2"} Rendered events/show.html.erb within layouts/application (3.7ms) Completed 500 Internal Server Error in 15ms Everything works locally and I have even pushed the database to heroku using db:push. Is there any more robust logging for heroku than the lines above that aren't helpful? ruby-on-rails-3 heroku internal-server-error share|improve this question asked Jul 18 '11 at 2:19 Msencenb 3,16473766 1 do you get errors when you visit the page that http://stackoverflow.com/questions/6728131/debugging-heroku-500-server-error does not require database connection? try heroku rake db:migrate –user482594 Jul 18 '11 at 2:35 add a comment| 2 Answers 2 active oldest votes up vote 7 down vote accepted I'm sure its because you haven't ran rake db:migrate If that does not work make sure that all the gems you need are in your Gem file, i.e. you are not making any local require statements to gems not in the Gemfile. What I have found helpful is tailing the log. And then you need to run this in console: heroku logs --tail Now click on the same page you were getting problems at before and check out the logs. EDIT: on rails 4 you'll need to add the rails_12factor gem to get the detailed logs. share|improve this answer edited Apr 2 '15 at 0:04 Charlie Egan 1,22141536 answered Jul 18 '11 at 12:24 s84 26.6k2694141 The actual problem I discovered was in the fact that I had accidentally made a foreign key even_id into a string instead of an integer and postgre didn't like that at all. That being said however I did discover it after upgrading to the expanded logging addon so your advice was spot on –Msencenb Jul 18 '11 at 17:05 I'm actually having the same problem. I need the foreign key to be a string and I was wondering how you managed to fix this?

Other errors, such as application errors (a 404 or 500), will display your application’s error page and not the Heroku error page. Only system-level errors that result in no response, or a malformed one, will display the Heroku error page discussed here. Debugging Logs are the first place to look when your users report seeing the Heroku error pages. Use the internal server error heroku logs command to view the unified event stream for your application and the state of the Heroku platform components supporting your application. $ heroku logs 2011-03-01T16:16:29-08:00 heroku[web.1]: State changed from starting to crashed 2011-03-01T16:16:59-08:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/ host=myapp.herokuapp.com fwd=17.17.17.17 dyno= connect= service= status=503 bytes= In this example, the router tried to serve a page for the app, but the web process is crashed. The Error H10 log entry contains the error code H10 that identifies the cause of this particular issue. Refer to the full list of error codes to determine the cause of the error you’re seeing. To learn more about tracking down errors that may lead to the error pages being generated, visit the article on Logging. Customize pages The pages displayed to your users when the application encounters a system error or is placed in the maintenance state can be customized. Customizing these pages allows you to present a more consistent UI to your users. Create and store the custom pages Create your custom pages as static HTML. You may wish to use the default HTML served by Heroku as a template: http://s3.amazonaws.com/heroku_pages/err
Slavko Vorkapitch (tstevens21) on 2014-04-24 19:51 We're sorry, but something went wrong. For some reason I am getting this error with my heroku app (this is only happening with the users portion when I try to sign_up, the other model functionality on postgresql seems to be cool) - I have done a heroku pg:reset heroku run rake:db:migrate, etc.. but to no avail.
