Grafana upgrade via Helm is failing - UPGRADE FAILED: resource mapping not found for name: "grafana"

I am trying to upgrade grafana using helm.

Error: UPGRADE FAILED: resource mapping not found for name: "grafana" namespace: "" from "": no matches for kind "PodSecurityPolicy" in version "extensions/v1beta1"```
what could this be?
it seems the grafana helm chart this uses this [https://github.com/grafana/helm-charts/blob/main/charts/grafana/templates/tests/test-podsecuritypolicy.yaml](https://github.com/grafana/helm-charts/blob/main/charts/grafana/templates/tests/test-podsecuritypolicy.yaml)
does the mean it is an issue on my end?

What version of Kubernetes are you running? If it is a version that doesn’t support PSPs then you can probably disable them in the values you pass to helm upgrade
