Means that the library hasn't been loaded. Check the network tab in the dev tools to confirm that it is showing a `404` response code (not found). If it is, you know that either someone has changed the HTML to the wrong script link, you've changed something in the version of VueJS you have loaded into the uibuilder library manager.

If you share some more info and maybe some code from your html file, we may be able to assist further.
