"Uncaught ReferenceError: epi is not defined" when displaying a form (the new episerver forms)

As the title says I am getting an client side error when displaying an episerver form in the view. The form is only a textbox and a submit button. This is where the debugger points at ()

GetFormInitScript?formGuid=a0639452-1cfc-4007-9f7b-7cd0ba73d527&formLanguage=en:6 Uncaught ReferenceError: epi is not defined

(function initializeOnRenderingFormDescriptor() {
    // each workingFormInfo is store inside epi.EPiServer.Forms, lookup by its FormGuid
    var workingFormInfo = epi.EPiServer.Forms["a0639452-1cfc-4007-9f7b-7cd0ba73d527"] = { // code ommited }

All I have done is basically downloaded the nuget package, version 0.21.1.9000, created a form, dragged into a content area and outputted it using Html.PropertyFor(). What am I doing wrong? Thanks for the help!
