Dashboard import in k8s not working using helm

I am trying to import the dashboards and have the datasource set to prometheus. Following is my configmap. The dashboard id is 405. I am able to manually import it but its not working with helm
apiVersion: v1
kind: ConfigMap
metadata:
name: custom-dashboards
labels:
app: {{ template “grafana.name” . }}
chart: {{ template “grafana.chart” . }}
release: {{ .Release.Name }}
heritage: {{ .Release.Service }}
data:
{{ (.Files.Glob “custom-dashboards/node.json”).AsConfig | indent 4}}

in values.yaml i have it set as
dashboardProviders:
dashboardproviders.yaml:
apiVersion: 1
providers:
- name: ‘default’
orgId: 1
folder: ‘’
type: file
disableDeletion: false
editable: true
options:
path: /var/lib/grafana/dashboards/default
- name: ‘ds2’
orgId: 2
folder: ‘’
type: file
disableDeletion: false
editable: true
options:
path: /var/lib/grafana/dashboards/ds2

dashboardsConfigMaps:
default: “istio-grafana-configuration-dashboards”
ds2: “custom-dashboards”

The dashboard related to istio are all visible when Grafana gets deployed. but the custom-dashboard is not visible in GUI. in the logs i see no errors .
configmaps appears to be correct
kubectl get cm/custom-dashboards -n monitoring -o yaml
apiVersion: v1
data:
