I'm not sure if there has been a recent update with Google App Script or not, but I've been using this script for a few months and it is now broken and not working.
Here's the script I am using:

if (parts[0] == '') parts.shift(); // Did path start at root, '/'?
var folder = DriveApp.getRootFolder();
for (var i = 0; i < parts.length; i++) {
var result = folder.getFoldersByName(parts[i]);
if (result.hasNext()) {
folder = result.next();
} else {
throw new Error( "folder not found." );
}
}
return folder;

Essentially, the script checks for emails with the label "gmail2drive" and if it exists, extracts the attachments in the email and uploads it to a folder called "Swann" in my Google Drive. Then it applies the label "to-gdrive/processed" to the processed emails, so they don't get processed again.
Occasionally, some attachments may be extracted twice, creating duplicates. So the script also checks for duplicates as well and hopefully prevents that from happening.
So this has been working fine for the most part, but recently it broke, resulting in the issue where the same attachments get extracted multiple times, and the same emails get processed multiple times. It's like the script ignores the label "to-gdrive/processed" or something.
I have tried using different labels and the result is the same.
I should also clarify that I am not a programmer or a scripting guy. I know just very very little in how to get this set up in Google Script. I can follow general instructions OK. I'm hoping for somebody who knows how to read scripts be able to troubleshoot this and let me know what to change.
Thanks in advance.
After many comments and a chat conversation, we deduced that this issue is produced by the DVR new emails being treated as replies of a thread. This was messing with the labels and causing to repeat uploads to the Drive folder.
New script:
Assuming there is a rule in the inbox that attaches the label "gmail2drive" to the threads received from the DVR, this gets all the threads with that label, processes each message of each thread and re-sends it as a new email. It also changes the subject with a Date (including milliseconds), so it makes sure each new email has a different subject and is independent from the others. After processing all the messages, sends the thread to the Bin.
function OrganiseEmails() {
var threads = GmailApp.search("-in:trash -in:drafts -in:spam label:gmail2drive -label:to-gdrive-processed")
for (i in threads){
var messages = threads[i].getMessages();
for (j in messages){
if (messages[j].getAttachments().length > 0){
var to = messages[j].getTo();
var date = Utilities.formatDate(new Date(), "GMT","yyyy-MM-dd' at 'HH:mm:ss:SS' '");
var subject = "DVR motion detected - " + date;
var body = "test";
var attachment = messages[j].getAttachments()[0];
var options = {
attachments: attachment
}
GmailApp.sendEmail(to, subject, body, options);
}
}
var rem_label = GmailApp.getUserLabelByName("gmail2drive");
rem_label.removeFromThread(threads[i]);
threads[i].moveToTrash();
}
}
I made some changes to the Gmail2Drive and Config.gs script as now it's not going to filter by label but by subject:
Code.gs
getOrCreateLabel(). We are not using a filter in this script so it's not necessary.var label = getOrCreateLabel(config.processedLabel); for obivous reasons.+ " -label:" + config.processedLabel from the gSearchExp variable declarationthread.addLabel(label); to thread.moveToTrash();Config.gs
in:inbox to the globalFilter search parameters to avoid threads being processed again because now they are also in Sent."processedLabel": "to-gdrive/processed","filter" from "label:gmail2drive" to "subject:'DVR motion detected - '"EDIT
Finally we decided to put both codes together, so create a new function in the code.gs and call it first in the Gmail2Drive function. Also, instead of changing labels you can delete the emails permanently with
Gmail.Users.Threads.remove("me", threadid); after sending the emails.
