iOS + Parse Cloud Code - updating a specific user (not logged in user)

Question

I am trying to update a user (Which is not the current user). I figured that you have to use cloud code to make the update.

I have created the cloud function below to update the selected user. I am trying to add meetingId's to an array property which belongs to User class.

Cloud Code:

Parse.Cloud.define('updateUser', function(request, response) {

               var userId = request.params.userId,
               meetingId = request.params.meetingId;

               var User = Parse.Object.extend('_User'),
               user = new User({ objectId: userId });

               user.addUnique("meetingsArray", meetingId)


               user.save(null, {userMasterKey:true}).then(function(user) {
                                response.success(user);
                                }, function(error) {
                                response.error(error)
                                });

               });

Objective-C //meetingId - is obtained from Meeting Object.

  [PFCloud callFunctionInBackground:@"updateUser" withParameters:@{@"objectId":user.objectId, @"meetingsArray":meetingId} block:^(NSString *result, NSError *error)
     {
         if (!error) {
             NSLog(@"%@",result);
         }else if(error){
             NSLog(@"%@", error);
         }
     }];

When I run the app - I get the following error code:

Error Domain=Parse Code=141 "The operation couldn’t be completed. (Parse error 141.)" UserInfo=0x1704f2780 {code=141, temporary=0, error={"code":201,"message":"missing user password"}, originalError=Error Domain=NSURLErrorDomain Code=-1011 "The operation couldn’t be completed. (NSURLErrorDomain error -1011.)"}

I'm new to Cloud code - i just basically want to update the array that belongs to the selected user and add a meetingId to it. Any help would be greatly appreciate it.

There are a few problems with the code that will prevent it from working:

1. the cloud code expects the meeting id parameter to be named @"meetingId", so change the parameters passed to @{@"objectId":user.objectId, @"meetingId":meetingId}

2. use Parse.User, not '_User' to extend user.

3. get - don't build - the user being updated

Summing up...

Parse.Cloud.define('updateUser', function(request, response) {
    var userId = request.params.userId;
    var meetingId = request.params.meetingId;

    var query = new Parse.Query(Parse.User);
    query.get(userId).then(function(user) {
        user.addUnique("meetingsArray", meetingId);
        return user.save(null, {useMasterKey:true});
    }).then(function(user) {
        response.success(user);
    }, function(error) {
        response.error(error);
    });
});
