Hi
In step unit 10 Create the deployment pipeline

When running the workflow build-latest.yaml

I'm getting the following error on Run Helm Deploy step:

Error: unable to build kubernetes objects from release manifest: unable to recognize "": no matches for kind "Ingress" in version "v1"
Error: Process completed with exit code 1.

This is how my workflow looks like:

__name: Build and push the latest build to staging

branches: [ main ]

build_push_image:
runs-on: ubuntu-latest

steps:
  - uses: actions/checkout@v2

    with:

      registry: ${{ secrets.ACR_NAME }}
      repository: contoso-website
      tags: latest

_deploy:

        --namespace staging \
        contoso-website \
        ./kubernetes/contoso-website \
        --set image.repository=${{ secrets.ACR_NAME }} \
        --set dns.name=${{ secrets.DNS_NAME }}__

Please advise_

It seems like the Ingress.yaml manifest is in old version format and need to be updated to the current Ingress version.
This is the current ingress.yaml manifest:

apiVersion: v1
kind: Ingress
metadata:
  name: contoso-website
  namespace: {{ default "staging" .Release.Namespace }}
  annotations:
    kubernetes.io/ingress.class: addon-http-application-routing
spec:
  rules:
    - host: contoso.!DNS!
      http:
        paths:
          - backend:
              serviceName: contoso-website
              servicePort: http
            path: /

Any advise on how to re-write it and update it to recent versions?
