Version of Helm and Kubernetes: Helm: version.BuildInfo{Version:"v3.2.1", GitCommit:"fe51cd1e31e6a202cba7dead9552a6d418ded79a", GitTreeState:"clean", GoVersion:"go1.13.10"}
Kubernetes: 1.16.8-gke.15 (Google Kubernetes Engine)
Which chart in which version: fluentd-elasticsearch, currently published public version (9.3.0)
What happened: When attempting to apply the fluentd-elasticsearch chart, I get an error: $ helm upgrade fluentd kiwigrid/fluentd-elasticsearch -f ./fluentd-values.yaml Error: UPGRADE FAILED: template: fluentd-elasticsearch/templates/service.yaml:4:48: executing "fluentd-elasticsearch/templates/service.yaml" at <.Capabilities.KubeVersion.GitVersion>: nil pointer evaluating interface {}.KubeVersion
What you expected to happen: I expect the chart to be applied successfully.
How to reproduce it (as minimally and precisely as possible): $ helm upgrade fluentd kiwigrid/fluentd-elasticsearch
Anything else we need to know: In troubleshooting this, I've noticed that GitVersion is deprecated. It is no longer listed at https://helm.sh/docs/chart_template_guide/builtin_objects/ and I see this mentioned here: https://github.com/helm/helm/blob/2f4ef705a9e8ea0e38a2c99c29c5e4de59b03d75/pkg/chartutil/capabilities.go#L60
I cloned the repo and tried using Version instead of GitVersion, thinking this to be the problem, but the behavior did not change.
If I scope the $striped_version definition to be global (by prepending $), then everything works as I'd expect. Here's a diff comparing current master to my local branch that works successfully: https://github.com/mchesnut/helm-charts/commit/a69a2787a8b2d88031632eeac7196980a4ea56da
