How to serve static files on CloudFoundry?

I have a svelte project that basically is a database of links to internal or external files represented visually as a table. Nothing uber-fancy.

So, I've read in other post on StackOverflow that I have to implement a route in order to properly serve static files. I ended up with the following code that perfectly works locally: the execution reaches the code, correctly defines the path of the file and serves the file to browser

the code is put into /src/routes/[...path/+server.js] file:

import path from 'node:path'import fs from 'node:fs/promises'import { error } from '@sveltejs/kit'import { defineConfig } from 'vite';export const GET = async ({ params }) => {    console.log("i've got the params ", params);    const workingFolder = import.meta.env.WORKING_DIR;    console.log("here is my url ", import.meta.url)    const pathName = `${workingFolder}/static${params.path}`;    console.log("here is the full path: ", pathName);    try {        const file = await fs.readFile(pathName);        return new Response(file, {            headers: {'Content-Type': getMimeType(pathName),            },        });    } catch {        throw error(404, 'File not found.');    }}function getMimeType(filePath) {    const ext = path.extname(filePath).toLowerCase();    const mimeTypes = {'.html': 'text/html','.css': 'text/css','.js': 'application/javascript','.json': 'application/json','.png': 'image/png','.jpg': 'image/jpeg','.gif': 'image/gif','.svg': 'image/svg+xml','.txt': 'text/plain',    };    return mimeTypes[ext] || 'application/octet-stream';}

the log output is usually something like it:

i've got the params  { path: '/uploads_folder/cls/20241216-01/9Mb-report.html' }here is my url  file:///C:/projects/project_name/src/routes/[...path]/+server.jshere is the full path: C:\projects\project_name/static/uploads_folder/cls/20241216-01/9Mb-report.html

Hovewer when I deploy that code to CloudFoundry VM, my code encounters '404 / not found' error and it seems like it never reaches this branch of code, as no log messages available in the logs.

my vite.config.ts is:

export default defineConfig({    plugins: [sveltekit()],    test: {        include: ['**/*.{test,spec}.{js,ts}']    },    define: {'import.meta.env.VERSION': JSON.stringify(version),'import.meta.env.WORKING_DIR': JSON.stringify(process.cwd()),    },    server: {        fs: {            strict: false,        },    }});

My deployment manifest.yml is also nothing fancy:

---applications:  - name: mywebsite    memory: 1G    instances: 1    routes:      - route: mywebsite.mycloudfoundry.com    stack: cflinuxfs4    buildpacks:      - https://github.com/cloudfoundry/nodejs-buildpack    services:      - serviceOne      - database    env:      PUBLIC_ENVOY_URL: "https://myenvoy.mycloudfoundry.com/"      BODY_SIZE_LIMIT: 25M

What blocks the route (or alters that) so the code is never reached and how to correct it?
