Uncaught TypeError: Failed to construct 'URL': Invalid base URL problem!

Ionic Framework ionic-v3
1

Good Afternoon,
I’m trying to develop my first android app using ionic 6 and vue 3, but I’m having this problem:
“Uncaught TypeError: Failed to construct ‘URL’: Invalid base URL” and it refers to my index.js.

This is my index.js code:

// eslint-disable-next-line no-unused-vars
import { createRouter, createWebHistory } from ‘@ionic/vue-router’;
import RenPlus from ‘@/views/ren/RenPlus.vue’;

const routes = [
{
path: ‘’,
redirect: ‘/folder/renplus’
},
{
path: ‘/folder/renplus’,
name: ‘RenPlus’,
component: RenPlus,
},
]

const router = createRouter({
history: createWebHistory(),
routes,
});

console.log(routes)

console.log(‘pippo’)
console.log(process.env.BASE_URL)

export default router;

// const router = createRouter({
// history: createWebHistory(process.env.BASE_URL),
// routes
// })

// const router = createRouter({
// history: createWebHistory(process.env.BASE_URL),
// //linkExactActiveClass: ‘active’,
// linkActiveClass: ‘active’,
// routes,
// });

// router.beforeEach((to, from, next) => {
// const requiresAuth = to.matched.some(record => record.meta.requiresAuth);
// const isAuthenticated = firebase.auth().currentUser;
// console.log(“isauthenticated”, isAuthenticated);
// if (requiresAuth && !isAuthenticated) {
// next(“/login”);
// } else {
// next();
// }
// });

and this is my main.js code:

/* eslint-disable */

import { createApp } from ‘vue’

import App from ‘./App.vue’

import router from ‘./router’;

import { IonicVue } from ‘@ionic/vue’;

/* Core CSS required for Ionic components to work properly */

import ‘@ionic/vue/css/core.css’;

/* Basic CSS for apps built with Ionic */

import ‘@ionic/vue/css/normalize.css’;

import ‘@ionic/vue/css/structure.css’;

import ‘@ionic/vue/css/typography.css’;

/* Optional CSS utils that can be commented out */

import ‘@ionic/vue/css/padding.css’;

import ‘@ionic/vue/css/float-elements.css’;

import ‘@ionic/vue/css/text-alignment.css’;

import ‘@ionic/vue/css/text-transformation.css’;

import ‘@ionic/vue/css/flex-utils.css’;

import ‘@ionic/vue/css/display.css’;

/* Theme variables */

import ‘./theme/variables.css’;

const app = createApp(App)

.use(IonicVue)

.use(router);

app.mount(‘#app’);

// router.isReady().then(() => {

// app.mount(‘#app’);

// });

Thank you!
