Deploy multiple jupyterhub instances in the same namespace

Hi,
is deploying multiple instances in the same namespace supported?
I get error trying for the second time with news name: invalid ownership metadata; annotation validation error: key “meta.helm.sh/release-name” must equal “jh2”: current value is “jh1”

I saw this topic.

tried to add:
hub:
extraEnv:
HUB_NAMESPACE:
name: HUB_NAMESPACE
valueFrom:
fieldRef:
fieldPath: metadata.namespace
PREFIXED_HUB_NAMESPACE:
value: “jh2-$(HUB_NAMESPACE)”

but it still failing.

Thank you,
Yan
