Helm Error converting YAML to JSON: yaml: line 20: did not find expected key

Solution 1
Here this problem happens because of indent. You can resolve by updating
env: {{- include "envs.var" .Values.secret.data | nindent 12 }}
Solution 2
Simplest way to resolve this kind of issues is to use tools.
These are mostly indentation issues, and can be resolved very easily using the right tool
npm install -g yaml-lint
yaml-lint is one such tool
PS E:\vsc-workspaces\grafana-1> yamllint .\grafana.yaml
× YAML Lint failed for C:/Users/mnadeem6/vsc-workspaces/grafana-1/grafana.yaml
× bad indentation of a mapping entry at line 137, column 11:
restartPolicy: Always
^
PS E:\vsc-workspaces\grafana-1> yamllint .\grafana.yaml
√ YAML Lint successful.

I don't really know what is the error here, is a simple helm deploy with a _helpers.tpl, it doesn't make sense and is probably a stupid mistake, the code:
deploy.yaml
apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2 kind: Deployment {{ include "metadata.name" . }}-deploy spec: selector: matchLabels: app: nginx replicas: 2 # tells deployment to run 2 pods matching the template template: metadata: labels: app: nginx spec: containers: - name: nginx image: nginx:1.14.2 ports: - containerPort: 80 vars: {{- include "envs.var" .Values.secret.data }}
_helpers.tpl
{{- define "envs.var"}} {{- range $key := . }} - name: {{ $key | upper | quote}} valueFrom: secretKeyRef: key: {{ $key | lower }} name: {{ $key }}-auth {{- end }} {{- end }}
values.yaml
secret: data: username: root password: test
the error
Error: YAML parse error on mychart/templates/deploy.yaml: error converting YAML to JSON: yaml: line 21: did not find expected key
