restartPolicy issue

Question

I have a app wanna deploy to AKS, it usually occur some error then the pod gonna restart, so I modify the yaml, here it is.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: testapp
spec:
  replicas: 1
  selector:
    matchLabels:
      app: testapp
  template:
    metadata:
      labels:
        app: testapp
    spec:
      nodeSelector:
        "beta.kubernetes.io/os": linux
      containers:
      - name: testapp
        image: mycr.azurecr.io/testapp:20210420
        command: ["/opt/testapp/bin/run"]
        ports:
        - containerPort: 8080
          name: testapp
      restartPolicy: Never

But when I submit the yaml it declined with such things: Failed to create the deployment 'testapp'. Error: Invalid (422) : Deployment.apps "testapp" is invalid: spec.template.spec.restartPolicy: Unsupported value: "Never": supported values: "Always"
