The call getOAuthToken returns null value - what am I missing?-CodePudding

I need to use a file picker in Apps Script, and I've tried the sample code from the Google Documentation but its not working - the ScriptApp.getOAuthToken() call is returning null.

I've followed all the instructions to change to a Standard Cloud Project and enabled the Google Picker API, but its just not happy.

So it turns it was actually the call DriveApp.getRootFolder() that was failing in the function provided in the sample code:

function getOAuthToken() {
    try {
        DriveApp.getRootFolder();
        return ScriptApp.getOAuthToken();
    } catch (e) {
        // TODO (Developer) - Handle exception
        Logger.log('Failed with error: %s', e.error);
    }
}

While the sample code works correctly without this call, I discovered the reason for the error was that I needed to enable the Google Drive API after switching to a Standard Cloud Project (required to run the Google Picker API).
