Exporting folder information from Shared Drive; Issue with pageToken - google-apps-script

Question

I'm attempting to export the folder name, folder id, folder url, and filepath for folders within a Shared Drive. This part works, but I'm limited to 100 items. I'm attempting to use the pageToken/nextPageToken functionality to pull all items, but it doesn't seem to work and continues returning only 100 items. I'm using the same basic structure as google uses in their example code for this purpose and was also referencing this solution to a similar problem.
function getFolderURLs() {
var folders, pageToken;
var foldersArray = [["Folder Name", "Link", "Folder ID", "Filepath"]]
do {
try {
var optionalArgs = {
supportsAllDrives: true,
includeItemsFromAllDrives: true,
pageToken: pageToken,
maxResults: 100,
q: '"132vqY8oyd6xKpnxxxxxxxxxxx" in parents and trashed = false and mimeType = "application/vnd.google-apps.folder"'
}
var folders = Drive.Files.list(optionalArgs);
var allFolders = folders.items
if (!allFolders || allFolders.length === 0) {
Logger.log ('No folders found.');
return
}
for (i = 0; i < allFolders.length; i++) {
var folder = allFolders[i];
var name = folder.title
var link = folder.alternateLink
var id = folder.id
var parentID = Drive.Files.get(folder.id,{
supportsAllDrives: true,
}).parents[0].id
var parent = Drive.Files.get(parentID,{
supportsAllDrives: true,
includesItemsFromAllDrives: true,
}).title
var filepath = `${parent}/${name}`
foldersArray.push([name, link, id, filepath])
}
pageToken = folders.nextPageToken;
} catch (err) {
Logger.log('Failed with error %s', err.message);
}
}
while (pageToken);
var ss = SpreadsheetApp.create('Clients Folder ID Listing');
var sheet = ss.getActiveSheet();
sheet.getRange(1,1,foldersArray.length, 4).setValues(foldersArray)
Logger.log(foldersArray)
}

Answer 1

I believe your goal is as follows.
You want to retrieve the folder list in the specific folder.
The specific folder has multiple subfolders.
You want to achieve this using Google Apps Script.
When I saw your script, Drive.Files.get is used in a loop. In this case, the process cost might be high. And, in your script, it seems that the subfolders cannot be retrieved.
In this case, how about the following sample script? In this answer, I used a Google Apps Script library for retrieving the file and folder list using Google Apps Script. I created this library for like this situation.
Usage:
1. Install library.
Please install the Google Apps Script library. You can see the method for installing it at here.
2. Enable Drive API.
This script uses Drive API. So, please enable Drive API at Advanced Google services.
3. Sample script:
function myFunction() {
const folderId = "###"; // Please set the folder ID.
const obj = FilesApp.getAllFoldersInFolder(folderId);
if (obj.id.length == 0) return;
const foldersArray = [["Folder Name", "Link", "Folder ID", "Filepath"], ...obj.name.map((e, i) => {
const folderName = e.pop();
const folderId = obj.id[i].pop();
return [folderName, `https://drive.google.com/drive/folders/${folderId}`, folderId, e.join("/")];
})];
const sheet = SpreadsheetApp.create('Clients Folder ID Listing').getActiveSheet();
sheet.getRange(1, 1, foldersArray.length, 4).setValues(foldersArray);
}
When this script is run, the folder list is retrieved from the specific folder. In this case, the subfolders are included. And, the values of "Folder Name", "Link", "Folder ID", "Filepath" are put into the created Spreadsheet.
In this script, the folder list in the shared drive can be retrieved. When I tested this, I confirmed that a folder list including more than 100 folders could be retrieved.

FilesApp: Google Apps Script library.
