In an Angular 4 web app with Internet Explorer 11 i get this error:
Unable to get property 'configurable' of undefined or null reference
relative to this lines:
// only attempt to set the name if's configurable (which it should be on node > 0.12)
if (Object.getOwnPropertyDescriptor(generateUUID, 'name').configurable) {
Object.defineProperty(generateUUID, 'name', {value: name});
}
