Fetch as Google doesn't render Angular.js application
<p>I have an Angular app that i'm trying to set up in production enviroment. As i have read, Google now is able to crawl through AJAX pages. I'm checking how i'd work with Fetch as Google service. Though the home page is correctly rendered in all major browsers, Fetch as Google returns blank page with none of Angular's directives compiled and no errors. I am using HTML5 mode and <code>ui-router</code>. Files are served by node.js app server (I have tried to serve files from nginx and result was the same) and all files are allowed by <code>robots.txt</code>. Scripts are concatenated and minified. There are no errors in console. </p>

<p>Code returned by Fetch as Google service:
    !doctype html>

<p>Is there something that was done wrong or should I just go with prerendering for crawlers?</p>
