Ember-Cli, Rails and Torii Session 400 Bad Request

Question

I am new to ember-cli, currently I am having trouble with oauth2 with LinkedIn, the server side is rails. This is also my first question so please let me know if there's any other information needed or if it's too verbose. When i attempt to sign in I get the linkedin popup but then get the following error:

POST http://localhost:9000/v1/sessions 400 (Bad Request) jQuery.ajaxTransport.send @ jquery.js:9664jQuery.extend.ajax @ jquery.js:9215exports.default.Ember.default.Object.extend._fetchSession @ application.js:22initializePromise @ ember.debug.js:45486Promise @ ember.debug.js:47114_fetchSession @ application.js:21fetch @ application.js:15(anonymous function) @ session.js:72tryCatch @ ember.debug.js:45439invokeCallback @ ember.debug.js:45451(anonymous function) @ ember.debug.js:47350(anonymous function) @ ember.debug.js:26472Queue.invoke @ ember.debug.js:878Queue.flush @ ember.debug.js:943DeferredActionQueues.flush @ ember.debug.js:748Backburner.end @ ember.debug.js:173Backburner.run @ ember.debug.js:228Backburner.join @ ember.debug.js:247run.join @ ember.debug.js:15904run.bind @ ember.debug.js:15966jQuery.Callbacks.fire @ jquery.js:3148jQuery.Callbacks.self.fireWith @ jquery.js:3260jQuery.extend.ready @ jquery.js:3472completed @ jquery.js:3503

I get the same response when I actually hit the 'sign in with linkedin' button.

Here is my code for ember-cli:

app/adapters/application.js

    import DS from 'ember-data';

export default DS.RESTAdapter.extend({
  namespace: 'v1'
});

app/routes/application.js

    import Ember from 'ember';
//takes place of App.IndexRoute =
export default Ember.Route.extend({
  //allow session to persist after page refreshes & fetch wehn activated
  //shoudl only happen once
  activate: function() {
    this.get('session').fetch();
  },

  actions: {
    signInViaLinkedin: function(){
      var route = this;

       this.get('session').open('linked-in-oauth2').then(function(authorization){
        // do the things after login, like redirect to dashboard
      }, function(error) {
        route.controller.set('error', 'Could not sign you in: ' + error.message);
      });
    }
  }
});
