how to read values from templatecache?

Question

I have generated a minified angular app with grunt. In the site I get an error:

Cannot GET /views/tabs.html

However when I look in the minified script.js I can see:

angular.module("app").run(["$templateCache", function($templateCache) {
    "use strict";
 $templateCache.put("views/tabs.html", '<div>hello</div>'}
]);

How can I resolve this error? Why is it not visible to the application?
