I'm trying to upgrade Elasticsearch from 7.17.3 to 8.1.0 with helm chart, but with new helm chart its giving me error.

```auto
Error: UPGRADE FAILED: template: elasticsearch/templates/statefulset.yaml:303:27: executing "elasticsearch/templates/statefulset.yaml" at <.Values.roles.master>: can't evaluate field master in type interface {}

```

Any lead and suggestion will be very helpful.
