Google Apps Script: copy document comments?

Google Apps Script: copy document comments? References I\'m working on the following script, which is supposed to look at the current document, grab its comments, make a copy, and copy the comments to the new document. However, I seem stuck. I\'m not actually sure how to grab and copy the comments. \".getComments\" and \".setComments\" seems to fail. What am I missing? function onOpen() { // Add a menu with some items, some separators, and a sub-menu. DocumentApp.getUi().createMenu(\'Copy Comments\') .addItem(\'Copy with comments\', \'copyDocument\') .addToUi(); } function copyDocument(e) { var app = DocumentApp.getActiveDocument(); var origId = app.getId(); var origName = app.getName(); var origFile = DocsList.getFileById(origId); //Set the scope var scope=\"https://www.googleapis.com/auth/drive\"; // GET the comments from the original Document var listUrl = \"https://www.googleapis.com/drive/v2/files/\" + origId + \"/comments\"; var originalComments = listUrl.getComments(); // Make a copy of the Document and store the ID var newFileId = origFile.makeCopy(\'Copy of \' + origName).getId(); // Set the URL to POST to var newUrl = \"https://www.googleapis.com/drive/v2/files/\" + newFileId + \"/comments\"; // Write the comments to the new Document var insert = originalComments.setComments(newURL); }
