[berlincount]

given

persistence:
  enabled: true
  size: 4Gi
  existingClaim: unifi-controller
  storageClass: ""
  annotations: {}
  accessModes:                                                                                                                                                                                   - ReadWriteOnce

I get

$ helm3 -n unifi-controller install unifi-controller midokura/unifi -f unifi-controller-values.yaml
rror: template: unifi/templates/statefulset.yaml:102:33: executing "unifi/templates/statefulset.yaml" at <.Values.persistence.existingClaim>: existingClaim is not a method but has arguments
