Received a error message when installation when Grafana Ingress is enabled and hosts are specified

I added this part in values.yaml to enable Grafana ingress, but I received that error

PS C:\openebs-monitoring\monitoring\deploy\charts> helm --kube-context cluster114 install monitoring .
Error: INSTALLATION FAILED: template: openebs-monitoring/templates/NOTES.txt:12:12: executing "openebs-monitoring/templates/NOTES.txt" at <.paths>: can't evaluate field paths in type interface {}
PS C:\openebs-monitoring\monitoring\deploy\charts>

here my modification in values.yaml

...
grafana.ini:
      ## If you have Ingress, you need to change the root_url to match ingress path
      server:
        root_url: http://localhost:3000/grafana
....
ingress:
      ## If true, Grafana Ingress will be created
      ##
      enabled: true

      annotations:
        nginx.ingress.kubernetes.io/ssl-redirect: "false"
        nginx.ingress.kubernetes.io/rewrite-target: /$2
      path: /grafana(/|$)(.*)
      hosts:
        - default.dynamic.cluster114.local

but if I don't specify the hosts, It will pass

ingress:
      ## If true, Grafana Ingress will be created
      ##
      enabled: true

      annotations:
        nginx.ingress.kubernetes.io/ssl-redirect: "false"

      #hosts:
