Steps to reproduce the behavior:

Not sure, but the following information migh help:

Most users are in LDAP, but this user is local
This user did not have any tickets. I created one for him, but that does not fix the issue
I rebuilt the index already ( zammad run rake zammad:searchindex:rebuild )

What’s the request causing this traceback?

ocroquette · April 14, 2025, 11:33am

Sorry, I have updated the log snippet.

LKSK23 · April 25, 2025, 1:44pm

Hi,

we have the same issue.

After upgrading to zammad 6.5 (6.5.0-1745497009.7cf3eef2.bookworm) we get the same probleme with a LDAP-user.

I tried to delete the cache, but the problem still exists.

systemctl stop zammad
zammad run rails r ‘Rails.cache.clear’
systemctl start zammad

Any hints?

System-OS: Debian 12

Hello,
we also have the same issue here. Is there anything we can try or any news on what causes this problem?

Best Regards
Marco.
