Deployed App not displaying in IE10

help

I have a deployed app that works just fine in Safari, Chrome or Firefox. However, IE10 just shows me a blank screen. The app is being served from an Nginx proxy using Jkatzen’s opsworks recipes. Any ideas?

Any errors in console on IE10?

There are a couple, but I’m assuming they are to do with the code not loading properly. The un-built version loads up in IE just fine. It’s only the dockerized, built version that’s having issues.

So, the issue turned out to be IE and Collection Behaviours related. For some reason, the built version of the App was errorring out on a call to collection.attachBehaviour(name, options). This was not occurring in a locally run version. Switching out that call for CollectionBehaviours.attach(collection, name, options) solved the problem.
