Value apisix.vault.enabled does nothing

[JoonaHa]

Hello!
I'm trying to initialize Apisix with Vault integration enabled at start-up.
I have installed the Helm chart by running:

helm install apisix apisix/apisix --create-namespace  --namespace apisix --set apisix.vault.enabled=true --set apisix.vault.host=http://vault-active.vault.svc.cluster.local:8200 --set apisix.vault.prefix=apisix --set apisix.vault.token=root

But when I try to query the configured secrets. There is nothing there.

$ curl --request GET \
  --url http://127.0.0.1:9180/apisix/admin/secrets \
  --header 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1'
{"list":[],"total":0}

If I kubectl exec to the pod I can see the Vault configuration correctly in conf/config.yaml

Have I misunderstood something? Is the Vault configuration read when deployed in traditional mode?
The documentation does not mention any restrictions for apisix.vault.enabled
I have also made sure that there is not any old persistenvolumes for etcd so the aren't any lingering old database files .

Thank you in advance.
