Is this a BUG REPORT :

What happened: When trying to render the template I got

Error: render error in "fluentd-elasticsearch/templates/service.yaml": template: fluentd-elasticsearch/templates/service.yaml:10:3: executing "fluentd-elasticsearch/templates/service.yaml" at <include "fluentd-elasticsearch.labels" .>: error calling include: template: fluentd-elasticsearch/templates/_helpers.tpl:48:27: executing "fluentd-elasticsearch.labels" at <include "fluentd-elasticsearch.name" .>: error calling include: template: fluentd-elasticsearch/templates/_helpers.tpl:6:18: executing "fluentd-elasticsearch.name" at <.Chart.Name>: nil pointer evaluating interface {}.Name

What you expected to happen: render fluentd manifest
