"existsSync" is not exported by "__vite-browser-external", imported by "X".

[Nefcanto]

Describe the bug

I'm using Qwik. I'm trying to use fs in some of my files.

Based on this link I'm importing methods from fs this way:

import {
    existsSync,
    mkdirSync,
    readdirSync,
    readFileSync,
    unlinkSync,
    writeFileSync,
} from 'fs'

Yet when I run npm run build I get this error:

"existsSync" is not exported by "__vite-browser-external", imported by "X".

Reproduction

I can't reproduce it in your vite.new template

The point is that I'm using fs in an Endpoint in Qwik, and it's supposed to run on the server.
