User search not working (elasticsearch error)

Technical assistance
1

Infos:

  • Used Zammad version: 6.4.1
  • Used Zammad installation type: package
  • Operating system: Ubuntu 24.04
  • Browser + version: Google Chrome 134.0.6998.178

Expected behavior:

  • In user settings, find any user imported from LDAP

Actual behavior:

  • After entering any character in the user search bar, the message “no entries” is displayed
  • When I open the “System Report” tab, I get the response: StatusCode: 500
  • When trying to rebuild the index, I get the response: rake aborted!

Steps to reproduce the behavior:

  • I open the web version of Zammad, go to settings-Users-Enter the username in the search bar.
    P.S. the users were added via LDAP AD

Did you maybe accidentally select a role (e.g. Admin) - under the user search bar?

By default, the search is performed without roles, but if I select any role, the result does not change, now I found a couple of similar problems as I have, apparently elasticsearch does not work, I can not rebuild the index and in the web zammad when opening the system report tab - the output StatusCode: 500

Now I’m checking the work of elasticsearch, the check shows that everything works

root@zammad:/home/localadm# curl http://localhost:9200
{
  "name" : "zammad",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "gFHgqWsMR62H4hQiTcoCZg",
  "version" : {
    "number" : "8.17.3",
    "build_flavor" : "default",
    "build_type" : "deb",
    "build_hash" : "a091390de485bd4b127884f7e565c0cad59b10d2",
    "build_date" : "2025-02-28T10:07:26.089129809Z",
    "build_snapshot" : false,
    "lucene_version" : "9.12.0",
    "minimum_wire_compatibility_version" : "7.17.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"

When I try to rebuild the index I get the response: rake aborted!
