Orphaned Pages Script Error

I've created a new Voodoopad document and pasted in the code from here:

https://www.voodoopad.com/documentation/page-events/

into my VPPageEventScript page

When I open the "Orphaned Pages" page the console in VP opens with the following text:

TypeError: keys.length is not a function. (In 'keys.length()', 'keys.length' is 5)
line: 9
column: 32

And orphaned pages are not displayed.

Anyone know what the problem might be? This is a new VP doc and does have orphaned pages. I'm assuming something's wrong with the VPPageEventScript script for orphaned pages.

   Hi svs,

   This code should work instead:

   function makeOrphanedPage(document) {
   
       var linkedPages = {}; // using a hash table here because it's convenient.
       var orphanedPages = [];
       var summaryPageName = "Orphaned Pages";
   
       /* Collect all linked pages. */
       var keys = document.keys();
       for (i = 0; i < keys.length; i++) {
           var page = document.pageForKey(keys[i]);
   
           if (!page.isText() || (page.key() == "orphaned pages")) {
               continue;
           }
   
           var pageContent = page.dataAsAttributedString();
           var linkedPageNames = document.linkedPageNamesInAttributedString(pageContent);
   
           for (j = 0; j < linkedPageNames.length; j++) {
   
               linkedKey = linkedPageNames[j].vpkey();
   
   
               // ignore self links.
               if (!linkedKey.isEqualToString(page.key())) {
                   linkedPages[linkedKey] = "";
               }
           }
       }
   
       /* Now compare the linked pages with all pages to find the orphaned ones. */
       for (i = 0; i < keys.length; i++) {
           var key = keys[i];
           if (linkedPages[key] == null) {
               orphanedPages.push(key);
           }
       }
       
       /* Create a summary page and open it. */
       var summaryPage = document.createNewPageWithName(summaryPageName);
       summaryPage.setDataAsString(summaryPageName + "\n\n" + orphanedPages.join("\n"));
   }
   
   function pageWasOpened(document, page) {
       if (page.key() == "orphaned pages") {
           makeOrphanedPage(document);
       }
   }
   

   the keys.length() has been replaced with keys.length. I apologize for the trouble. We will update the documentation as soon as we can. Let me know if you run into anymore issues.
