HI team, We are trying to install k8s-monitoring chart of v0.12.0 and while installing we are facing an issue

Error: template: k8s-monitoring/templates/tests/test.yaml:106:54: executing "k8s-monitoring/templates/tests/test.yaml" at <index .Subcharts "grafana-agent">: error calling index: index of untyped nil

I have check in the repo list and i am able to see the grafana-agent chart as well. But not sure why the issue is.

Can you please help here as soon as possible.

Tried with 0.9.3 and latest version as well. But resulted in same issue.

HI Team & @skl , We are also facing the same issue. Helm Version : Version:"v3.11.3", GitCommit:"323249351482b3bbfc9f5004f65d400aa70f9ae7", GitTreeState:"clean", GoVersion:"go1.20.3"

Error: executing "k8s-monitoring/templates/tests/test.yaml" at <index .Subcharts "grafana-agent">: error calling index: index of untyped nil

Any help is much appreciated.

I just tested with Helm 3.11.3 and it worked fine. The line in question is: https://github.com/grafana/k8s-monitoring-helm/blob/v0.12.0/charts/k8s-monitoring/templates/tests/test.yaml#L106

Specifically, this section (index .Subcharts "grafana-agent"), which has Helm access the grafana-agent templates within the .Subcharts object. This is needed because we invoke the grafana-agent.fullname template.

With index of untyped nil: that makes me thing that .Subcharts is not defined.

How are you trying to deploy the chart? with the Helm cli? with Terraform or ArgoCD?

we are trying to deploy to aws eks cluster using https://github.com/unbroken-dome/gradle-helm-plugin Using above plugin, we are creating gradle task and deploying using that gradle task.

But, i see the grafana-agent chart in the repo list. So if it is already there, why it is showing up an error.

@petewall any update on this?

I'm not familiar with the gradle-helm-plugin. Does the helm install work correctly when using the Helm cli directly?

The error message is not indicating that it can't find the grafana-agent sub chart, it's indicating that it doesn't know what .Subcharts is. That's why I asked about the Helm cli version, since .Subcharts was introduced in version 3.7

Did you try this? Does it work with the Helm CLI?
