So I've been trying to fix this for days now and I'm beyond stuck.

My app is running, and I can access the site when I go to the default url (example.com). I can refresh on this url without issues, and I can navigate through the pages being rendered through react router as long as I don't refresh on any other page. (e.g.) refreshing on example.com/path1 doesn't work, I get a 404 error.

My current ingress file looks like:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: myApp-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
    cert-manager.io/cluster-issuer: letsencrypt-prod
    nginx.ingress.kubernetes.io/use-regex: "true"
spec:
  tls:
    - hosts:
        - my.app.com
      secretName: myApp-tls
  rules:
    - host: "my.app.com"
      http:
        paths:
          - pathType: Prefix
            path: /.*
            backend:
              service:
                name: myApp
                port:
                  number: 80

I've added many of the most common replies to issues such as this, but it only makes matters worse, such as white screen with "Unexpected token '<'" errors for all javascript files it tries to load, and none of the pages loading at all.

For example, I've tried:

    nginx.ingress.kubernetes.io/rewrite-target: /
    nginx.ingress.kubernetes.io/rewrite-target: /$1
    nginx.ingress.kubernetes.io/rewrite-target: /$2
    nginx.ingress.kubernetes.io/configuration-snippet: |
      try_files $uri $uri/ /index.html;

I've tried adding additional paths to the controller for each route available in the app, I've tried setting the path to just "/" or "/(.*)", nothing is working.

Any help would be greatly appreciated! thank you!

I've also tried doing it with CMD ["npx", "http-server", "./dist", "-p", "3000"] since the server part is only doing the following:

      this.app.use(express.static(path.resolve(__dirname, "../dist")));
      this.app.get("*", (request: express.Request, response: express.Response) => {
        response.sendFile(path.resolve(__dirname, "../dist/index.html"));
      });
