Weird 404 errors in `undefined:12`

Recently, I have been getting a lot of errors like:

GET http://localhost:3000/assets/index-b543198f.js net::ERR_ABORTED 404 (Not Found)

GET http://localhost:3000/assets/index-b543198f.js net::ERR_ABORTED 404 (Not Found)

in the console. Both in localhost as well as on the built&deployed site. it says this 404 happens in undefined:12. I'm a little stumped, because my site works fine, nothing seems to be missing. I don't know what index-b543198f.js is the line 12 of undefined is also unhelpful.

Could you please give a bit more context about your project? Classic template vs. Solid Start? What vite settings? Stale cache maybe?

@lexlohr of course, vite-template-solid and here's my vite config:

import { defineConfig } from 'vite';
import solidPlugin from 'vite-plugin-solid';
import suidPlugin from "@suid/vite-plugin";
import solidSvg from 'vite-plugin-solid-svg'

export default defineConfig({
  plugins: [suidPlugin(), solidPlugin(), solidSvg({ defaultAsComponent: false })],
  server: {
    port: 3000,
    proxy: {
      "/api": {
        target: "https://host.com",
        changeOrigin: true,
        secure: false,
        rewrite: (path) => path.replace(/^\/api/, "/api"),
      },
      "/images": {
        target: "https://host.com",
        changeOrigin: true,
        secure: false,
        rewrite: (path) => path.replace(/^\/images/, "/images"),
      },
    },
  },
  build: {
    target: 'esnext',
  },
  resolve: { // To fix aws-sdk and Vite failing to build on AWS Amplify
    alias: [
      {
        find: './runtimeConfig',
        replacement: './runtimeConfig.browser',
      },
    ]
  },
});

import { defineConfig } from 'vite';
import solidPlugin from 'vite-plugin-solid';
import suidPlugin from "@suid/vite-plugin";
import solidSvg from 'vite-plugin-solid-svg'

export default defineConfig({
  plugins: [suidPlugin(), solidPlugin(), solidSvg({ defaultAsComponent: false })],

Ah, you're using vite's template. I guess the issue is with your deployment. DId you invalidate previous deployments?

BersaelorOP•3y ago

for sure, after every new deploy, I run a cloudfront invalidation with /* (as part of the github action) but the issue mostly happens during development I have just "also" seen in happen in the deployed site from time to time

BersaelorOP•3y ago

in development it really happens every time I reload the page

BersaelorOP•3y ago

I mean it's mostly annoying, since it distracts from the issues I actually want to look at in the console ah, now it says images/undefined, thats new that gives a hint that it's an image thats not available during loading if I look into the Sources tab of chrome, I can't find any assets/index-....css file (since it's a 404)

BersaelorOP•3y ago

after reloading it's just undefined:12 again

BersaelorOP•3y ago

how would I clean the vite/solidjs cache? is it maybe liking some now outdated files?

Alex Lohr•3y ago

rm -r node_modules/.vite

BersaelorOP•3y ago

thank you, but unfortunately still the same console output afterwards I mean, the site seems to be working fine, it's just the unnecessary red-error spam in the console thats got me curious ok, so I did a rm -rf node_modules + yarn install + complete hard reload and clear caches in chrome now it'sgone

👍 Doing caching right is one of the hardest things.
