Would be good to see the whole project (a github link?), but you might try to edit package.json file and add "type": "module" `..." main": "app.js", "type": "module", "scripts": {...

I would try to console.log everything that is possible first to make sure if fx. `ifcModel` is actually loaded, so maybe try `console.log(ifcModel)`
