Asynchronous imports not working?

Question

Vue.js

Started refactoring the code and found out that dynamic import won't work without require("./components/Constructor/ConstructorControlPanel")

import bootstrap from 'bootstrap'
window.bootstrap = bootstrap;
import vue from "vue";
window.Vue = vue;
import store from './store/store'
require("./components/Constructor/ConstructorControlPanel");

new Vue({
    el: '#app',
    components: {
        Manager: () => import(/* webpackChunkName: "Manager" */ './components/Manager'),
        Constructor: () => import(/* webpackChunkName: "Constructor" */ './components/Constructor'),
        Viewer: () => import(/* webpackChunkName: "Viewer" */ './components/Viewer'),
    },
    store,
    beforeMount() {
        this.$store.dispatch('initStore');
    }
});

Error Any ideas?
