How to get site owner using JSOM/REST when logged in user has read only access.
currentContext.Site.Owner or REST API, fail with unauthorized access error. As it is just readonly property it should be available to all, but it is not.
EDIT: using REST I am trying
/_api/site/owner. or JSOM way
context.Site.Owner; I need site owner (Primary Administrator)
Any pointer? Thanks in advance
