Problem with Dgraph helm chart serviceAccount creation

@joaquin Problem solved by running helm upgrade repo dgraph. :laughing: I should have thought about it earlier! argggg… :rofl: Cheers! :beers:

Now I can see the serviceAccountName correctly returned.

helm install dgraph-release dgraph/dgraph \      
--namespace neosight --debug --dry-run \  
--values deploy/dev/dgraph/dgraph-values.yaml | grep serviceAccountName  

install.go:178: [debug] Original chart version: ""
install.go:195: [debug] CHART PATH: /Users/Ann.Zhang/Library/Caches/helm/repository/dgraph-0.2.2.tgz

      serviceAccountName: neosight-service-account-dev
      serviceAccountName: neosight-service-account-dev
