Vite not importing environment variables or secrets Laravel 9 deployment

Questions / Help Build debugging

So i was building my application but a major part of it requires environment variables from vite which
I am using laravel echo here:

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: import.meta.env.VITE_PUSHER_APP_KEY,
    cluster: import.meta.env.VITE_PUSHER_APP_CLUSTER ?? 'mt1',
    wsHost: window.location.hostname,
    wsPort: import.meta.env.VITE_PUSHER_PORT ?? 80,
    wssPort: import.meta.env.VITE_PUSHER_PORT ?? 443,
    forceTLS: false,
    disableStats: true,
    enabledTransports: ['ws', 'wss'],
});

But in the compiled file the environment variables are shown as empty/undefined: this is from the compiled file

window.Echo = new qy({
    broadcaster: "pusher",
    key: {}.VITE_PUSHER_APP_KEY,
    cluster: {}.VITE_PUSHER_APP_CLUSTER ?? "mt1",
    wsHost: window.location.hostname,
    wsPort: {}.VITE_PUSHER_PORT ?? 80,
    wssPort: {}.VITE_PUSHER_PORT ?? 443,
    forceTLS: !1,
    disableStats: !0,
    enabledTransports: ["ws", "wss"]
});

for example the key: is coming something like {}.VITE_PUSHER_KEY, this configuration works in development under npm run dev and build both, and is as per the naming convention of the prefix “VITE_” for import.meta variables in the vite docs. I have tried adding the variables as secrets but I still get the undefined variables in the compiled file
