Hi,

Anyone has worked on migrating from stable/prometheus-operator chart? I was following the instruction to migrate the chart, however, it was failed. Below was the error msg I received. And advice? Thanks.

❯ helm upgrade --install dev prometheus-community/kube-prometheus-stack --reuse-values --set nameOverride=prometheus-operator
