我最初使用以下命令安装了ingress-nginx：
helm install --name nginx-ingress stable/nginx-ingress --set rbac.create=true
我当前的版本是0.21.0，并且想升级到0.22.0
按照建议的in the official documentation，我正在运行以下命令：
helm upgrade --reuse-values nginx-ingress stable/nginx-ingress
但是我遇到以下错误：
Error: UPGRADE FAILED: render error in "nginx-ingress/templates/controller-servicemonitor.yaml": template: nginx-ingress/templates/controller-servicemonitor.yaml:1:86: executing "nginx-ingress/templates/controller-servicemonitor.yaml" at <.Values.controller.m...>: can't evaluate field enabled in type interface {}
