Problem with Dgraph helm chart serviceAccount creation

Here is my settings.

serviceAccount:
  create: true
  annotations:
    eks.amazonaws.com/role-arn: arn:aws:iam::xxxxxxxxxxx:role/demo-iam-role
  name: demo-service-account
  automountServiceAccountToken: true

Using these values above as test.yaml with K8S (EKS) 1.27 using both helm template or helm install --debug --dry-run, and I could not see any issue.

# template test
helm template dgraph/dgraph --namespace dgraph \
  --values test.yaml | grep -A11 -B3 ServiceAccount

# ---
# # Source: dgraph/templates/serviceaccount.yaml
# apiVersion: v1
# kind: ServiceAccount
# metadata:
#   name: demo-service-account
#   labels:
#     app: dgraph
#     chart: dgraph-0.2.1
#     component: alpha
#     release: release-name
#     heritage: Helm
#   annotations:
#     eks.amazonaws.com/role-arn: arn:aws:iam::xxxxxxxxxxx:role/demo-iam-role
# ---

# debug dry-run install test
helm install mydg dgraph/dgraph --namespace dgraph --debug --dry-run \
  --create-namespace --values test.yaml | grep serviceAccountName
#       serviceAccountName: demo-service-account
#       serviceAccountName: demo-service-account

I have also installed this with K8S (EKS) 1.26, with an IAM Role for S3 bucket access for backups, and have not encountered any issues. Though with this one, I used the default dgraph sa name.
