Failed to retrieve the values of a List of Groups property using REST

When I try this REST URI : .../wikis/xwiki/classes/XWiki.XWikiRights/properties/groups/values
I get this message :

Query statement = [select distinct doc.fullName as groupReference, doc.title as groupName from XWikiDocument doc, BaseObject obj where doc.fullName = obj.name and obj.className = 'XWiki.XWikiGroups' and doc.space = 'XWiki' and doc.name <> 'XWikiGroupTemplate' order by lower(doc.fullName), doc.fullName]
