Describe the bug

I have a vue app that works without problems when executed in kubernetes on a single pod without replication.
However, as soon as I try to replicate, it doesn't work anymore and it throws this kind of errors in the browser console when it tries to read content from node_modules/.vite (that I think is the vite cache):

Loading module from “https://srsproject.it/node_modules/.vite/deps/auth0.js?v=0a5335c3” was blocked because of a disallowed MIME type (“”).
Loading module from “https://srsproject.it/node_modules/.vite/deps/chunk-U6BEPC57.js?v=ddbe559a” was blocked because of a disallowed MIME type (“”).

Reproduction

Steps to reproduce

Install docker, kubectl and minikube
Download all files in the repo and cd into the folder
Run minikube delete
Run minikube start
Run helm install nginx-ingress ingress-nginx/ingress-nginx
In /etc/hosts pair srsproject.it with the ip returned by the command minikube ip
In another terminal, run minikube tunnel
Run kubectl apply -f .
Run kubectl delete ingress client-ingress
Run minikube dashboard
A dashboard window will open in your browser, go to "Deployments", open "client-deployment"
On the top right press "Scale resource" and scale it to 2
Open a browser tab, press CTRL+Shift +I, open srsproject.it in that window

The problem was that i was using the development version of the app on kubernetes. You must use the production version, that is generated with vite build or npm run build, if you have it configured in your package.json
