Storing arrays of text into Parse database

Question

I am creating a mail system where user A sends a piece of text to user B, user B stores the text in an array in a column called Inbox (which has the attribute array).

I create 5 users, the first 2 users responds with "POST https://api.parse.com/1/classes/_User/fjT08jUUk8 400 (Bad Request)"

HOWEVER, the last 3 users works perfectly fine. I'm really frustrated because I just can't figure out what the problem is. All the users are created with the same conditions.

I'll link the code used here:

<textarea name="msg" id="msg" rows="10" cols="60"></textarea>
<button ng-click="sendMessage(fetched_user.id)">Send</button>

(fetched_user.id is the corresponding id for the user you're targeting, double checked it)

$scope.sendMessage = function(UID) {     
    var query = new Parse.Query(Parse.User);

    query.equalTo('objectId', UID);
    query.first({
        success: function(object) {
            var text = $('#msg').val();
            object.add("Inbox", text );
            object.save();
            $scope.$apply();    
        },
        error: function(error) {
        alert("Error: " + error.code + " " + error.message);
        }

    });
}

As always I'm really greatful for any kind of answer!! Thanks in advance :)

SOLVED!!!!

After a lot of research I found that object.save() was the problem and that it was giving me this error: Error: 206 Parse::UserCannotBeAlteredWithoutSessionError

I believe that this is some kind of security measure, that not everyone can alter users as they like. This has to be done from cloud code, which per say is a whole other department. So for you guys who want to get this done, get your reading into Parse Cloud Code!

您可以使用request.user获取任何云函数的调用用户， request.user是指向用户的指针，应使用该指针而不是传递objectId。
