App crashed because of syntax error in an helper utf-8 encoded

Question

Dear all.

I'm using heroku to deploy my app (rails 3). Ok so I do the usual, which is a git commit, a git push heroku master => deployment is ok, gems are installed, etc...

When running my app in the web browser, I get an heroku error : app crashed.

In the ouput of heroku logs, this got my attention :
==> dyno-2625316.log (crash) <==
/disk1/home/slugs/321697_5debeb5_58eb-de03f9a2-bd41-487c-aae7-6b20b9281d85/mnt/.bundle/gems/ruby/1.8/gems/activesupport-
3.0.0/lib/active_support/dependencies.rb:239:in `require': /disk1/home/slugs/321697_5debeb5_58eb-de03f9a2-bd41-487c-aae7
-6b20b9281d85/mnt/app/helpers/string_helper.rb:6: syntax error, unexpected kEND, expecting $end (SyntaxError)

It seems that there's a syntaxt error in my string_helper module. This file is encoded in utf-8 (I precise it because it can be important).

This file contains the following lines (empty) :

module StringHelper




end

Note : I had a groups_helper file with methods in it, and the app crashed because of that. I deleted it and now the error points to this stringhelper.

What I will do now : delete this file an redeploy.

Edit I did delete string_helper. Now the error is on events_controller.rb, the very same error

==> dyno-2625316.log (crash) <==

-8631c932a62b/mnt/app/controllers/events_controller.rb:104: syntax error, unexpected kEND, expecting $end (SyntaxError)

line 104 is the last end of the class

class EventsController < ApplicationController

  layout 'event'

  def index
  end

  ...

end

This file is also in utf-8

Answer 1

Id definately is an encoding problem. All my controllers and helpers were encoded in utf-8. I changed it to ansi, solved my problem.

I opened a ticket on heroku.
