Как передать значение переменной .Files.Glob на диаграмме Хелма?

Question

Вызов .Files.Glob ниже должен быть из переменной, предоставленной как значение из .Values.initDBFilesGlob. Значение устанавливается правильно, но условие if не соответствует истине, даже если .Values.initDBConfigMap пусто.

Как передать аргумент переменной в .Files.Glob?

Шаблон, о котором идет речь (templates/initdb-configmap.yaml из моего графика WIP https://github.com/northscaler/charts/tree/support-env-specific-init/bitnami/cassandra, который я отправлю на https://github.com/bitnami/charts/tree/master/bitnami/cassandra в качестве PR, как только это будет исправлено):

{{- $initDBFilesGlob := .Values.initDBFilesGlob -}}
# "{{ $initDBFilesGlob }}" "{{ .Values.initDBConfigMap }}"
# There should be content below this
{{- if and (.Files.Glob $initDBFilesGlob) (not .Values.initDBConfigMap) }}
apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ include "cassandra.fullname" . }}-init-scripts
  labels: {{- include "cassandra.labels" . | nindent 4 }}
data:
{{ (.Files.Glob $initDBFilesGlob).AsConfig | indent 2 }}
{{- end }}

Файл values.yaml:

dbUser:
  forcePassword: true
  password: cassandra
initDBFilesGlob: 'files/devops/docker-entrypoint-initdb.d/*'

Команда: helm template -f values.yaml foobar /Users/matthewadams/dev/bitnami/charts/bitnami/cassandra

Там - это файлов в files/devops/docker-entrypoint-initdb.d относительно каталога, из которого я Я вызываю команду.
