Crawling Ember-FastBoot application

I have a Ember-FastBoot application that I'm trying to crawl using http://ift.tt/1zByED0

The FastBoot server is working well as I can use my website without javascript.

But when I crawl for example http://localhost:4200/pages/index, it uses the base index.html and not the index served by FastBoot. Like the crawler adds .html to the route which default to base index.html.

Any clues would be appreciated
