OpenWhisk cannot be installed in Microk8s due to error: serviceaccount "default" not found

I have a single node Kubernetes cluster, with Microk8s (1.26/stable) installed with snap, on Linuxmint (Ubuntu derivation).

I have installed helm too, more precisely helm 3.7/stable. Installed with snap command.

Using helm, I have tried to install OpenWhisk on this single node using this yaml for the helm command:

helm install owdev openwhisk/openwhisk -n openwhisk --create-namespace -f whisk.yaml

The whisk.yaml file contents is:

whisk:
  ingress:
    type: NodePort
    apiHostName: localhost
    apiHostPort: 31001
    useInternally: false

nginx:
  httpsNodePort: 31001

# disable affinity
affinity:
  enabled: false
toleration:
  enabled: false
invoker:
  options: "-Dwhisk.kubernetes.user-pod-node-affinity.enabled=false"
  # must use KCF as kind uses containerd as its container runtime
  containerFactory:
    impl: "kubernetes"

Once the command is executed, I get the following error:

Error: INSTALLATION FAILED: pods "owdev-wskadmin" is forbidden: error looking up service account openwhisk/default: serviceaccount "default" not found

Any idea of what I made wrong?

The following command is executed to get the secrets:

microk8s kubectl get secrets --all-namespaces

It was missing the ingress addon on microk8s. Removing using helm openWhisk, adding ingress addon on microk8s, and re executing the openWhisk command:

helm install owdev openwhisk/openwhisk -n openwhisk --create-namespace -f whisk.yaml

OpenWhisk get installed.
