[adminsyss]

Used Zammad Version

6.5.2

Environment

• Installation method: source
• Operating system Debian 12
• Database + version: 15.16
• Elasticsearch version: 8.19.13
• Browser + version: Latest Chroùe

Actual behaviour

Hello,

When I add a GitLab issue to a ticket, it no longer works because, since the latest GitLab (18.10) update, issues have become work items, so the new URL is: https://{GITLAB_URI}/{GROUP}/{GROUP}/-/work_items/{ISSUE_ID}

Whereas previously the issue URL was: https://{GITLAB_URL}/{GROUP}/{GROUP}/-/issues/{ISSUE_ID}

The capture of the error in zammad-production.log:

E, [2026-03-23T09:47:35.258577#692985-17181760] ERROR -- : Invalid GitLab issue link format (Exceptions::UnprocessableEntity)

Expected behaviour

The option to add a resolution to a ticket is now working again

Steps to reproduce the behaviour

Add Gitlab Issue in zammad ticket on a gitlab with the latest version 18.10

Support Ticket

No response

I'm sure this is a bug and no feature request or a general question.

I can confirm the issue. If you manually correct the URL, it works because the old URL from gitlab.com is still being used.
The Docker Compose version is being used.

We can confirm this issue with Gitlab v18.10.0-ee and Zammad 7.0.0.

Additionally, existing linked Issues seem to be broken too. In a Zammad ticket where I previously linked a GitLab Issue, the Gitlab Icon menu button has the "1" indicating one linked Issue, but the list in the right sidebar is empty:
