I'm experiencing a frustrating scenario with dynamic imports in Vue 3 when using route lazy loading. I have a Vue Router setup where certain components are lazily loaded, but occasionally when I navigate to these routes, I get a 404 behavior. Here's a simplified version of my router configuration: ```javascript import { createRouter, createWebHistory } from 'vue-router'; const routes = [ { path: '/home', component: () => import('./views/Home.vue'), }, { path: '/about', component: () => import('./views/About.vue'), }, { path: '/:catchAll(.*)', redirect: '/home', }, ]; const router = createRouter({ history: createWebHistory(), routes, }); export default router; ``` I've checked that the components exist in the specified paths and they seem to load fine most of the time. However, sometimes when I try to hit the '/about' route directly, I end up seeing a 404 behavior. The console shows the following behavior: ``` [Vue Router warn]: Failed to resolve route with name 'about'. ``` To troubleshoot this, I verified that my web server is correctly configured to serve the application and handle history mode. I've also tried clearing the browser cache and even switching browsers, but the scenario continues. I suspect it might be related to how and when the components are being loaded, or possibly a timing scenario with how the routes are resolved. Could this be due to the asynchronous nature of dynamic imports? Have others faced similar issues, and are there any best practices or configurations I should consider to avoid these 404 errors when navigating directly to lazy-loaded routes? The project is a web app built with Javascript. Thanks in advance!
