When I deploy the following I get this error:

Error:

  Error: UPGRADE FAILED: render error in "marketplace/templates/front-ingress.yaml": template: marketplace/templates/front-ingress.yaml:36:30: executing "marketplace/templates/front-ingress.yaml" at <include "marketplace...>: error calling include: template: marketplace/templates/_helpers.tpl:6:18: executing "marketplace.name" at <.Chart.Name>: can't evaluate field Chart in type string

marketplace.name is defined in _helpers.tpl:

{{- define "marketplace.name" -}}
{{- default .Chart.Name .Values.nameOverride | trunc 63 | trimSuffix "-" -}}
{{- end -}}

.Chart.Name is an internal variable and the order of preference is explained here but even setting nameOverride the error is the same.

The strange thing is if I remove this template, .Chart.Name works fine within any other template so I think the problem is related to the scopes of the range used.
