Everything works locally during development, but deploying to Heroku fails with:

I am building the Ember applications styles from the ember-cli styles directory using SASS.

Any ideas?

[jmdfm]

Took a cue from the stack trace including manifest.rb, and included this in my Brocfile.js:

var app = new EmberApp({
  fingerprint: {
    generateRailsManifest: true
  }
});

But no dice :(

[jmdfm]

I should note, I am deploying to a staging Heroku environment. So I tried to ensure that the asset-rev always runs with this:

var app = new EmberApp({
  fingerprint: {
    enabled: true,
    generateRailsManifest: true
  }
});

But still nothing.

[rwz]

First off, Ember fingerprinting and generateRailsManifest SHOULD both be disabled. Second, what version of the EmberCLI Rails are you using? Third, is there a reason you're using the version of Rails that was released more than a year ago and received eleven bugfix releases since then?

[rwz]

Assuming you're using the latest version of ember-cli-rails, is there a chance you could build a minimal showcase app to demonstrate the error?

[rwz]

Also, what happens when you run RAILS_ENV=production rake assets:precompile locally?

[jmdfm]

Where is it documented that 'Ember fingerprinting and generateRailsManifest SHOULD both be disabled.'? This seems to be a vital piece of information and there's nothing covering it.

I'm using Ember-CLI 0.1.12.

Yes, there's a very good reason. I have no control over it. Unfortunately I don't live in a magical greenfield consulting land where I can enjoy everything new, all the time.

😿

Cheer up, there's nothing that should be preventing the gem from working properly on Rails 4.0.2. It's a bug and we'll try to fix it, so it's gonna be all good.

Rails manifest is disabled by default and our magical addon takes care of disabling the fingerprinting.

The idea behind the gem was that the integration should be as seamless as possible and the whole experience should be very Rails-like. The assumption is that it should work with default settings, which it kind of does. If you're messing with deployment-related options, you must be knowing what you're doing better than we do.

[jmdfm]

Ultimately it was nothing to do with Sprockets.

Because of this nonsense (https://github.com/rwz/ember-cli-rails/blob/master/lib/ember-cli/app.rb#L18) an exception that was being thrown by Ember-CLI was being completely swallowed when deploying on Heroku.

Don't swallow output, please.

@johnmcdowall Getting this same error - would you mind sharing how you resolved it?

[gordonbisnor]

I'm getting this as well, Rails 4.1.9, ember-cli-rails 0.1.11, ember-cli 0.2.0 –– would be curious to hear how you fixed or debugged.

[thewatts]

I think there is a solution on #112 --> but I haven't had a chance to validate yet.

[jmdfm]

For me, there was an exception being thrown elsewhere because of a missing asset file, that at the time was being swallowed by ember-cli-rails:

#82

[tigershen23]

@johnmcdowall how were you eventually able to track that down?
