Hello, I’m trying to use the Kubernetes ingress controller ([GitHub - kubernetes/ingress-nginx: Ingress NGINX Controller for Kubernetes](https://github.com/kubernetes/ingress-nginx)) and have tried to setup a defaultBackend with helm.

While it does look like 404 pages are responding with my custom defualtBackend, I’m noticing that unhandled 5xx+ (and potentially others) pages are still returning with the default ingress controller’s error pages… any idea on how I can have all 400+ default error pages point to my defaultBackend?

Example values file:

```auto
defaultBackend:
  enabled: true
  image:
    repository: my-custom-default-backend
    tag: "latest"
    pullPolicy: Always
    readOnlyRootFilesystem: false
  port: 8080

```

Example ingress resource where I tried an invalid configuration to try and see my default backend (but it didn’t show it):

```auto
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: blei-test-ingress
  namespace: default
  annotations:
    nginx.ingress.kubernetes.io/auth-response-headers: Authorization,Cookie
    nginx.ingress.kubernetes.io/auth-url: https://google.com
spec:
  ingressClassName: nginx-ingress
  rules:
    - host: hello.localdev.me
      http:
        paths:
          - path: /
            pathType: ImplementationSpecific
            backend:
              service:
                name: invalid-service
                port:
                  number: 8080

```
