And create template with this code:

#{if (%{‘${Description}’.equals('')})}
None
#{end}
#{if (%{!’${Description}’.equals('')})}
${wiki:Description}
#{end}

-----------
#{if (%{"${Description}".equals('')})}
None
#{end}
#{if (%{!"${Description}".equals('')})}
${wiki:Description}
#{end}

How to reproduce

Actual result/Attachments
No data is being generated when mapping the field with '${Description}', with "${Description}" works!
