Why do I get an Invalid Argument when using the removeLabel function in Google Script

Question

I'd like to remove my user created label called "Add-to-Spendee-2", from a collection of emails. I've pretty much followed Google's removeLabel() Documentation to the dot on this, but I keep getting an "Invalid argument: label" error.

Here's the code:

 function removeLabel() { var myLabel = GmailApp.getUserLabelByName('test-add-to-spendee-2'); var threads = GmailApp.search("label:test-add-to-spendee-2 AND from:swiggy AND subject:(Your receipt for Swiggy order)"); for (var x in threads) { var thread = threads[x] thread.removeLabel(myLabel) } }

Note: If I substitute the removeLabel(myLabel) with any other function like markUnread() , the code works perfectly.

Answer 1

I think your code will work but I think all you need to do is:

var lbl=GmailApp.getUserLabelByName('Q0/Subject/Name');
var threads=GmailApp.search('label:Q0/Subject/Name');//exactly as you created it
lbl.removeFromThreads(threads);

Try using the debugger and make sure that threads is getting an array of GmailThread objects.

This is what the label look like in the Gmail search window:

They changed the slashes to dashes and used lower case and that's not really what the label looks like.

As I said above in my comment:

I just did that recently and I found that the description of the label in the gmail search window did not agree with how I actually created the label. It displayed a label like this q0-subject-name and I had it created as Q0/Subject/Name when I used q0-subject-name I couldn't find the label and when I used Q0/Subject/Name I found it.
