I can run helm install --name rabbitmq stable/rabbitmq with no problems.

I want to download the chart and install it from local files. I get the tgz with helm fetch stable/rabbitmq then unzip it with tar -xvzf rabbitmq-4.1.0.tgz --warning=no-timestamp. Everything is now in a folder called rabbitmq (templates folder, Chart.yaml, values.yaml, etc)

Now if I run helm install -n rabbitmq ./rabbitmq/ -f ./rabbitmq/values.yaml I get:

Error: render error in "rabbitmq/templates/configuration.yaml": template: rabbitmq/templates/configuration.yaml:18:48: executing "rabbitmq/templates/configuration.yaml" at <4>: invalid value; expected string

That line 4 is name: {{ template "rabbitmq.fullname" . }}-config

Why isn't this value getting replaced properly? Is there some extra step I need to do when helm installing a chart from local files?
