my yaml is: 
apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
  name: harbor-tls
  namespace: harbor
spec:
  secretName: harbor-tls
  issuerRef:
    name: letsencrypt-prod
    kind: ClusterIssuer
  commonName: harbor.mydomain.com
  dnsNames:
  - harbor.mydomain.com
ho to fix the secretname to harbor-tls?
