Hi,  
I am trying to install Rancher 2 using following api object:

```auto
apiVersion: helm.cattle.io/v1
kind: HelmChart
metadata:
  creationTimestamp: "2021-04-22T09:47:03Z"
  finalizers:
  - wrangler.cattle.io/helm-controller
  generation: 3
  name: rancher
  namespace: kube-system
  resourceVersion: "2177"
  uid: bd42926e-355a-49d6-ab28-b15331067363
spec:
  chart: rancher
  repo: https://releases.rancher.com/server-charts/stable
  set:
    hostname: rancher-test.com
    http_proxy: http://example-wproxy.test.com:8080
    https_proxy: https://example-wproxy.test.com:8443
    ingress.tls.source: secret
    no_proxy: 127.0.0.0/8\\,10.0.1.0/8
  targetNamespace: cattle-system
status:
  jobName: helm-install-rancher

```

However, I have a problem with commas in no\_proxy variable. I am aware that I have to escape commas, but even if I add two \ helm-install fails.

```auto
helm_v3 install --namespace cattle-system --repo https://releases.rancher.com/server-charts/stable --set-string hostname=rancher-test.com --set-string http_proxy=http://example-wproxy.test.com:8080 --set-string https_proxy=https://example-wproxy.test.com:8443 --set-string ingress.tls.source=secret --set-string rancher rancher
Error: must either provide a name or specify --generate-name

```

From job logs it seems that no\_proxy part is missing, there is nothing atfer last --set-string

And when I don’t escape comma i get an error about it:

```auto
helm_v3 install --namespace cattle-system --repo https://releases.rancher.com/server-charts/stable --set-string hostname=rancher-test.com --set-string http_proxy=http://example-wproxy.test.com:8080 --set-string https_proxy=https://example-wproxy.test.com:8443 --set-string ingress.tls.source=secret --set-string no_proxy=127.0.0.0/8,10.0.1.0/8 rancher rancher

Error: failed parsing --set-string data: key map "10" has no value

```

I also tried adding a different amount of \ and other " and more more, unfortunately with no success.  
My k3s version is v1.20.4+k3s1

Is it even possible to add commas in variables of HelmChart object? and how to fix it ?

Ok, it was a bug, and it is already fixed.

I am aware that helm requires to escape a comma sign, but I guess somehow when helm-install starts, it does something weird to this setting.
