Suddenly can't sync due to "Invalid label name" but no idea which label might be causing the problem

I've been using lieer for a few years now and it's generally been great (thank you), but recently I've been unable to sync due to the following error message:

googleapiclient.errors.HttpError: <HttpError 400 when requesting https://gmail.googleapis.com/gmail/v1/users/REDACTED/labels?alt=json returned "Invalid label name". Details: "[{'message': 'Invalid label name', 'domain': 'global', 'reaso
n': 'invalidArgument'}]">

I've checked my notmuch tags using notmuch search --output=tags '*' but nothing looks amiss to me. How can I find which tag is being choked on?

try running again the sync, pull, or posh, with -v, then -vv and check all 1 to 3 lines exactly before the error, it can be that you have a tag/label that cannot be pushed to gmail

Okay, I might have had the same problem. I tried using --logging_level without any luck, but when I did a gmi sync --dry-run I got to see the tags. In my case it's pretty obvious that it's the '\x1b' tag that's causing trouble.

❯ gmi sync --dry-run
dry-run: True

(dry-run) gid: 193f801307f449fa: add: [], remove: ['INBOX']

I could then search for the tag and remove it.

❯ notmuch dump | grep '1b '
+%1b +inbox +sent -- id:202501180.....

Hope this helps you.
(\x1b is ascii control code 'escape', so I guess there is an input in either neomutt or alot that accepted me pressing ESC as a tag)
