Error from Engine (showDialog) - Cannot read property 'then' of undefined.

There is a potential bug with Qlik Engine error handling.

The issue is when an error occurs in the Qlik engine such as "Error code: 5 (Access Denied), it is followed by an exception from within require.js.  Instead of showing an error dialog, this leaves our iframe blank.

We can code around this on non-single object apps by binding a function to the qlikApp.model.session.Error, and handling the error on our own, but when loading a single app in an iframe we are unable to because of cross-domain.

I've attached a screenshot of the errors from console.

Console log displays the EXPECTED error due to Section Access, but it appears to error when trying to display the error dialog (showDialog):

Error from Engine: Object error: Object code: 5 message: "Access denied"parameter: ""__proto__: Object__defineGetter__: __defineGetter__()__defineSetter__: __defineSetter__()__lookupGetter__: __lookupGetter__()__lookupSetter__: __lookupSetter__()constructor: Object()hasOwnProperty: hasOwnProperty()isPrototypeOf: isPrototypeOf()propertyIsEnumerable: propertyIsEnumerable()toLocaleString: toLocaleString()toString: toString()valueOf: valueOf()get __proto__: __proto__()set __proto__: __proto__()id: 1 jsonrpc: "2.0"__proto__: Object

Error:
