javascript - associating an array of photos with a user on parse.com -

i'm trying upload several user photos parse.com , associate them user object. i'm using javascript sdk https://www.parse.com/docs/js_guide#objects-types i'm able save photo file object. when try build array column in user object/table sdk errors out.

i error json.stringify cannot serialize cyclic structures. upon saving user object.

profilecontroller.js

// uploads photo rest api given local file_uri $scope.addphoto = function() {    var file = new parse.file("profile-image.jpeg", { base64: $scope.imagedata });   file.save().then(function(res) {     console.log('success', res);     var array = ['foo', file];     $scope.user.set('photos', array);     $scope.user.save();   }, function(error) {       console.log('error', error);   }); }; 

this error arises when object being serialized holds references itself. question - there way associate user image files user object on parse.com? ideally array column because know there never more 5 profile images per user.

pictureholder.class

 {"photos":["url": $parsefile1, "url":$parsefile2, "url":$parsefile3...]} 

_user contains following pointer column.

{"linkphotos":{"__type":"pointer","classname":"pictureholder","objectid":$id_pointed_to}}

flat query on _user table add following query.parms...

 include=linkphotos 

that inline json response, full, linked row 2nd table.
