ExtendScript for Updating Links on InDesing 2014

Hello everybody

I am using this a script to update the image links inside my INDD files, but I am unable to use it on my inDesign 2014. Does anybody know what changed on the latest version that the method update(); is no longer updating the links?

Here follows the code I have done to update the links

app.scriptPreferences.userInteractionLevel = UserInteractionLevels.NEVER_INTERACT; 

var numberOfEntriesFound = 0;

start();

function start() {

    var targetFolder = Folder.selectDialog("Select a magazine folder to search for INDD files:");

    var targetFolderPath;

    if (targetFolder != null) {

        targetFolderPath = targetFolder.fsName;

    } else {

         exit();

    }

    var topFolder = (new Folder(targetFolderPath));

    forEachDescendantFile(topFolder, doStuffIfdocument);

    if (numberOfEntriesFound == 0) {

         alert('Process finsihed: No INDD were found under the given folder.');

    } else {

         alert('Process finsihed: ' + numberOfEntriesFound + ' INDD files were updated.');

    }

}

function forEachDescendantFile(folder, callback) {

    var aChildren = folder.getFiles();

    for (var i = 0; i < aChildren.length; i++) {

        var child = aChildren;

        if (child instanceof File) {

            callback(child);

        } else if (child instanceof Folder) {

            this.forEachDescendantFile(child, callback);

        } else {

            throw new Error("The object at \"" + child.fullName + "\" is a child of a folder and yet is not a file or folder.");

        }

    }

}

function doStuffIfdocument(oFile) {

    if (matchExtension(oFile, "indd")) {

        numberOfEntriesFound++;

        var document = app.open(oFile);

        try {

            doStuff(document);

        } finally {

            document.close(SaveOptions.YES);

        }

    }

}

function doStuff(document) {

    document.links.everyItem().update();

}
