Helm Chart - Range for Files.Get function to get content from file and put them in ConfigMap

Im trying to use recursion in order to be adding contents of files in the ConfigMap.yaml but i dont seem to get it right. I dont get the content of the file no matter what i try. The location of the file is correct because i can get the content without recursion. {{.Files.Get "config/gitlab.conf" | indent 4 -}}

Any help would be greatly appreciated! Thank you

ConfigMap.yaml:

{{- if .Values.volConfigMap}}
{{- range .Values.volConfigMap }}
---
apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ .config.configName }}
  namespace: {{ $.Release.Namespace }}
data:
{{- if  .config.file }}
{{- range $path, $config := .config.file }}
  {{ $path }}: |
{{ tpl ($.Files.Get $config) $ | indent 4 -}}
{{- end -}}
{{- end -}}
{{- end -}}
{{- end -}}

Values.yaml:

config:
        configName: gitlab-conf
        file:
          logstash.conf: config/gitlab.conf

OUTPUT:

apiVersion: v1
kind: ConfigMap
metadata:
  name: gitlab-conf
  namespace: elk
data:
  logstash.conf: |

The |- marker in YAML takes a multi-line string. This can be a useful technique for embedding big blocks of data inside of your manifests, as exemplified here.

{{- if .Values.volConfigMap }}
{{- range .Values.volConfigMap }}
apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ .config.configName }}
  namespace: {{ $.Release.Namespace }}
data:
  {{- if .config.file }}
  {{- range $k, $v := .config.file }}
  {{ $k }}: |-
    {{ $.Files.Get $v | nindent 4 }}
  {{- end -}}
  {{- end -}}
{{- end -}}
{{- end -}}
