Thread:Project:Support desk/Obtaining protection level with Categorymembers list/reply (2)

params = { 'action'   :'query', 'list'      :'categorymembers', 'cmtype'    :'page', 'cmtitle'   :u'Category:Articles amb referències puntuals demanades', 'prop'      :'info', 'inprop'    :'protection'}

That doesn't seem to work, I do not obtain any information about the protection level.
