I'm getting an error logged to the console:
GET http://localhost:3000/js/lib/angular/MINERR_ASSET 404 (Not Found)
I saw this post and it said it was a result of not inculding ngRoute module, but I do!
public/js/app.js:
window.app = angular.module('mean-blog-seed', ['ngCookies', 'ngResource', 'ui.bootstrap', 'ngRoute', 'mean-blog-seed.controllers', 'mean-blog-seed.services']);
Then I have a jade file that references angular-route.js:
script(type='text/javascript', src='js/lib/angular/angular.min.js')
script(type='text/javascript', src='js/lib/angular-route/angular-route.min.js')
script(type='text/javascript', src='js/lib/angular-cookies/angular-cookies.min.js')
script(type='text/javascript', src='js/lib/angular-resource/angular-resource.min.js')
script(type='text/javascript', src='js/lib/angular-bootstrap/ui-bootstrap-tpls.min.js')
script(src='js/app.js')
script(src='js/config.js')
script(src='js/services/global.js')
script(src='js/controllers/posts.js')
script(src='js/controllers/header.js')
script(src='js/filters.js')
script(src='js/directives.js')
The repo is here
Update: I posted the issue on github and got referenced to this crazy answer: https://github.com/angular/angular.js/issues/4675
The ng-closure-runner runs an angular specific pass during compilation which adds a definition for MINERR_ASSET, that asset is not included with any of the 1.2.x releases (the only releases with source maps). However, the source map references MINERR_ASSET as a source and as a result there is a 404 when requesting the file.
I've only quickly glanced at the grunt tasks and also ng-closure-runner, but I'm under the impression this is likely the ng-closure-runner included minErr.js or some file generated based on it. Either way the correct asset should be packaged with the other source files or MINERR_ASSET should be removed from the source map "sources".
