unknown flag: --size-buckets
Usage of :
unknown flag: --size-buckets

What happened:

I installed ingress-nginx using helm and tried to set the flag size-buckets as it looks that it exists https://github.com/kubernetes/ingress-nginx/blob/main/cmd/nginx/flags.go and according that feature described here https://github.com/kubernetes/ingress-nginx/pull/7171.

The ingress-nginx deployment is successful but the pod is not starting and get the following message in pod logs “unknown flag: --size-buckets”.

If try to use other flag, e.g. “enable-metrics” it works and accept the flag.

According the documentation at https://github.com/kubernetes/ingress-nginx/blob/main/docs/user-guide/cli-arguments.md, the flags time-buckets, length-buckets, size-buckets are not listed in list of arguments.

So the question is, how can I set these flags?
