Hello,
Call json() on a Response objet returns a type Object. I think it comes from here: https://github.com/angular/angular/blob/master/modules/angular2/src/facade/lang.ts#L333
Shouldn't the method return an Any type? Because, when you try to access a property of this object, you get a Typescript error: Property 'access_token' does not exist on type 'Object'.
Thank you very much,
Basile
