How to create a list of all folders in a shared goggle drive folder - google-apps-script

Question

I'm trying to create a listing of all my google drive folders and I have the following script and a link to the question where I got the script from. I'm just not sure how to implement it. I put the Drive ID in line 6 and then ran it and got this error; Can anyone tell me where I'm going wrong?
List every file and folder of a shared drive in a spreadsheet with Apps Script
11:08:37 AM Error
ReferenceError: gobj is not defined
getFoldersInASharedFolder # Folder Listing.gs:12
This is the script
function getFoldersInASharedFolder() {
let tr = [];
let token = '';
let page = 0;
do {
let r = Drive.Files.list({ corpora: 'drive', includeItemsFromAllDrives: true, supportsTeamDrive: true, supportsAllDrives: true, driveId: "???", pageToken: token,q: "mimeType = 'application/vnd.google-apps.folder'" });
let obj = JSON.parse(r);
tr.push(obj)
token = obj.nextPageToken
} while (token != null)
let folder = DriveApp.getFolderById(gobj.globals.testfolderid);
folder.createFile(`SharedDriveList ${Utilities.formatDate(new Date(), Session.getScriptTimeZone(), "MM/dd/yyyy HH:mm:ss")}`, JSON.stringify(tr), MimeType.PLAIN_TEXT);
let html = '<style>td,th{border:1px solid black;font-size: 16px;}</style><table><tr><th>Title</th><th>Id</th><th>Path</th></tr>';
tr.forEach((o, i) => {
o.items.forEach(item => {
if (item.mimeType = "application/vnd.google-apps.folder") {
html += `<tr><td>${item.title}</td><td>${item.id}</td><td>${getPathAllDrivesFromId(item.id)}</td></tr>`;
}
})
});
html += '</table><input type="button" value="exit" onclick="google.script.host.close()" />';
SpreadsheetApp.getUi().showModelessDialog(HtmlService.createHtmlOutput(html).setHeight(500).setWidth(1200), `Folders in: ${JSON.parse(Drive.Drives.get("driveid")).name}`);
}

Answer 1

The error message occurs because
let folder = DriveApp.getFolderById(gobj.globals.testfolderid);
use the a nested property of gobj as parameter but gobj was not declared.
You can fix this error either by properly declaring gobj or by replacing gobj.globals.testfolderid by the folder id (properly set as a string).

Answer 2

The comments explain how to use this function
function getFoldersInASharedFolder() {
const sharedriveid = "";//add the shared drive id here
const storagefilefolderid = ""; //this where I was storing the response which I used when I was first building the script. It's not necessary to do this if you don't wish to. You can just comment that code out of the script
let tr = [];
let token = '';
let page = 0;
do {
let r = Drive.Files.list({ corpora: 'drive', includeItemsFromAllDrives: true, supportsTeamDrive: true, supportsAllDrives: true, driveId: sharedriveid, pageToken: token,q: "mimeType = 'application/vnd.google-apps.folder'" });//drive id for the shared drive that you wish all of the folders from
let obj = JSON.parse(r);
tr.push(obj)
token = obj.nextPageToken
} while (token != null)
let folder = DriveApp.getFolderById(storagefilefolderid);//the folder id for the file that stores the results
folder.createFile(`SharedDriveList ${Utilities.formatDate(new Date(), Session.getScriptTimeZone(), "MM/dd/yyyy HH:mm:ss")}`, JSON.stringify(tr), MimeType.PLAIN_TEXT);
let html = '<style>td,th{border:1px solid black;font-size: 16px;}</style><table><tr><th>Title</th><th>Id</th><th>Path</th></tr>';
tr.forEach((o, i) => {
o.items.forEach(item => {
if (item.mimeType = "application/vnd.google-apps.folder") {
html += `<tr><td>${item.title}</td><td>${item.id}</td><td>${getPathAllDrivesFromId(item.id)}</td></tr>`;
}
})
});
html += '</table><input type="button" value="exit" onclick="google.script.host.close()" />';
SpreadsheetApp.getUi().showModelessDialog(HtmlService.createHtmlOutput(html).setHeight(500).setWidth(1200), `Folders in: ${JSON.parse(Drive.Drives.get(sharedrivedid)).name}`);
}
