I'm experiencing the same issue when calling this chart as a subchart. I've got a dashboard JSON in my parent chart, under files/dashboards/nginx-ingress/nginx-metrics.json, but it doesn't seem to render when using a similar config as the one posted above.

grafana:
  dashboards:
    nginx-ingress:
      nginx-metrics:
        file: files/dashboards/nginx-ingress/nginx-metrics.json
  dashboardProviders:
    dashboardproviders.yaml:
      apiVersion: 1
      providers:
      - name: nginx-ingress
        orgId: 1
        folder: 'nginx-ingress'
        type: file
        disableDeletion: false
        updateIntervalSeconds: 3
        options:
          path: /var/lib/grafana/dashboards/nginx-ingress

It'd be really helpful if someone could provide a full working example for supplying dashboard JSONs to this chart using local files.

I also ran into the same issue and resulted in using the sidecar/configmap dashboard option instead.

EDIT: This issue could also be related to https://github.com/helm/charts/issues/21638
