Hi Pulumi community - I am trying to get my hands dirty with pulumi kubernetes operator - I am trying to create a stack resource which will create an EC2 instance - I am using S3 backend.

apiVersion: <http://pulumi.com/v1|pulumi.com/v1>
kind: Stack
metadata:
  name: ec2-k8s-stack-3
spec:
  backend: "<s3://pulumi-test-backend-bucket>"
  #secretsProvider: "awskms:///<KMS KEY ARN>?region=<REGION>"  # optional - is used to initialize a Stack with alternative encryption
  envRefs:
    PULUMI_CONFIG_PASSPHRASE:
      type: Secret
      secret:
        name: pulumi-aws-secrets
        key: PULUMI_CONFIG_PASSPHRASE
        namespace: pulumi
    AWS_DEFAULT_REGION:
      type: Literal
      literal:
        value: us-west-2
    AWS_ACCESS_KEY_ID:
      type: Secret
      secret:
        name: pulumi-aws-secrets
        namespace: pulumi
        key: AWS_ACCESS_KEY_ID
    AWS_SECRET_ACCESS_KEY:
      type: Secret
      secret:
        name: pulumi-aws-secrets
        namespace: pulumi
        key: AWS_SECRET_ACCESS_KEY
#    AWS_SESSION_TOKEN:
#      type: Secret
#      secret:

There is only one single stack resource. Not sure why the stack is always remain locked and not getting unlocked. Any help will be appreciated . Thanks Rajendra Gosavi
