helm deploy xxx .. -f sm-onap.yaml

Portal was enabled in sm-onap.yaml file

However, it is not deployed and checked log file shows below message

_Release "prod-portal" does not exist. Installing it now.
Error: YAML parse error on portal/charts sm-onap.yaml /portal-app/templates/deployment.yaml: error converting YAML to JSON: yaml: line 53: did not find expected ',' or ']'_

However

helm upgrade xxx .. portal.enabled=true

will deploy portal

I am not sure whether this is a bug or not, but please provide me some guide to resolve this issue.

The line in deployment.yaml is

{{ include "common.aaf-config" . | indent 6 }}
      {{- end }}
      containers:
    *  - name: {{ include "common.name" . }}*
