Can't upgrade Rancher 2.3.2 after helm upgrade to v3

Rancher
1

Hello,

I tried to upgrade rancher from version 2.3.2 to 2.3.5, but earlier I had to upgrade helm from 2.16 to 3.0.3. I’ve done it using https://helm.sh/blog/migrate-from-helm-v2-to-helm-v3/

After that:

version.BuildInfo{Version:"v3.0.3", GitCommit:"ac925eb7279f4a6955df663a0128044a8a6b7593", GitTreeState:"clean", GoVersion:"go1.13.6"}

But now, when I try to upgrade Rancher:

  helm upgrade rancher rancher-stable/rancher \
>   --namespace cattle-system \
>   --set rancher.mycompany.com

Error: failed parsing --set data: key map “rancher” has no value

I have no idea what to do :slight_smile:
