if condition checking for defined is not enough

[aneeshkp]

.Values contains nodeselector:{}

The tool converts following template
{{- if .Values.nodeSelector }} nodeSelector: {{ end if }}
To
{% if nodeSelector is defined %} " nodeSelector: {% endif %}
The resulting out is :{} which is invalid yaml
Expected Template , to add codition to check if teh filed has length
{% if nodeSelector is defined and nodeSelector|length %}" nodeSelector: {% end if %}
