Google scripts, get a drive file url - google-apps-script

Question

I need my script to load the URL of a drive file to be added to a spreadsheet. For whatever reason 'File.getUrl()' returns null, but everything else seems to be working.
For example, 'File.getName()' works. So am I missing a permission or something?
Here is my code (abridged):
function loadURL(folderPath, name) {
var folder = loadFolder(folderPath);
// Find file
var files = folder.searchFiles('modifiedDate >= "' + getDate() + '" and title = "' + name + '"'),
file, found = 0;
for (; files.hasNext(); found++) {
file = files.next();
}
if (found == 1) {
/////////////////////////////////
// Here is 'getUrl'
/////////////////////////////////
var url = file.getUrl();
Logger.log("Loaded: " + url);
return url;
} else {
throw "Error loading file";
}
}
/**
* ** NOTE: THIS SEEMS TO BE WORKING FINE **
* Load a folder
* #param {string} url
* #return {Folder}
*/
function loadFolder(url) {
var folders = url.split('/'),
folder = DriveApp.getRootFolder();
Logger.log("Loading URL: " + url);
for (var key in folders) {
var fName = folders[key];
if (fName.length > 0) {
var fIt = folder.getFoldersByName(fName),
found = 0;
Logger.log(" -> " + fName);
for (; fIt.hasNext(); found++) {
folder = fIt.next();
}
if (found == 0) {
throw "Could not find the folder '" + fName + "'";
} else if (found > 1) {
throw "Found multiple matches to the folder '" + fName + "'";
}
}
}
return folder;
}
And the log if you're curious:
[14-02-26 19:56:15:980 EST] Loading URL: Work/PDF/
[14-02-26 19:56:15:981 EST] -> Work
[14-02-26 19:56:16:120 EST] -> PDF
[14-02-26 19:56:16:450 EST] Loaded: null
And if I change getUrl to getName it (kinda) works
[14-02-26 20:10:20:588 EST] Loading URL: Work/PDF/
[14-02-26 20:10:20:589 EST] -> Work
[14-02-26 20:10:20:727 EST] -> PDF
[14-02-26 20:10:21:058 EST] Loaded: Test

Answer 1

var url = DocsList.getFileById(fileId).getUrl();
Was recommended as a workaround by a poster on the issue thread that zig posted.
So, in your case, you'd use:
for (; files.hasNext(); found++) {
file = files.next();
}
if (found == 1) {
/////////////////////////////////
// Here is 'getUrl'
/////////////////////////////////
var fileId = file.getId();//new line added to getId of the file
//modified url line to reference doc by id
var url = DocsList.getFileById(fileId).getUrl();
Logger.log("Loaded: " + url);
return url;
} else {
throw "Error loading file";
}
I didn't get to test this right now because it's late and I'd have to build a the right structure to test it properly, but since you already have the structure change those two commented lines and let me know if that worked.

Answer 2

Using the id instead of the url works:
var url = "https://docs.google.com/document/d/" + file.getId() + "/";

Answer 3

Today started an issue with drive getUrl, google is aware of it and working on it.
Does work using docList or drive advanced services.
