Thanks for creating this script. Couple of issues:

• As well as installing bash 4, you may need to install jq - https://stedolan.github.io/jq/download/.
• The script was having trouble retrieving the personal access token from GitHub so I had to manually copy it into the .token file.

All working beautifully now. Thanks again!

I had an issue that caused the script to exit on each creation of a label. It ran without errors when updating. I was able to fix it by replacing line 71 with

HAS_ERROR=$(echo "$CURL_OUTPUT" | jq 'has("errors")')

and then using

if [ "$HAS_ERROR" = true ]; then

on line 73.
I forked it here: https://gist.github.com/MatthiasKunnen/b7c4f812ddc6a8bb217160ab4f048e0c.

Shame it doesn't work for Gitlab! Do you think that would be an easy thing to add?

Looks great, how would that work if you had users who didn't have 2FA enabled?
