After Update to 2.6 i can not see integrations


If you are a Zammad Support or hosted customer and experience a technical issue, please refer to: using your zammad-hostname / or company contract.

  • Used Zammad version: 2.6
  • Used Zammad installation source: (source, package, …) rpm
  • Operating system: centos 7
  • Browser + version: firefox

Actual behavior:

  • if i open Integration, the window are blank.
    an i can not search for Users

Steps to reproduce the behavior:

Maybe you could provide more details and or examine your zammad and elasticsearch logfiles

We cannot help you with missing information about database server (plus Version) and elasticsearch version.
I assume that your elasticsearch version is not matching.

elasticsearch 5.6.11-1.noarch
postgresql 9.2.23-3.e17_4

I just updated my Zammad test server to verify the ES version. Everything works fine for me with the following:

You can not search for users but are all users listed in admin -> manage -> users?

Can you verify that the elasticsearch plugin ingest-attachment is installed?

sudo /usr/share/elasticsearch/bin/elasticsearch-plugin list

And do the log files show any error as I already asked earlier?

Another interesting question would be:
Did you use integrations in Zammad before and if yes, which ones?

Exception in thread “main” java.lang.UnsupportedClassVersionError: org/elasticsearch/plugins/PluginCli : Unsupported major.minor version 52.0

no because the major problem is this with the user tap

{“error”:“undefined method `last_owner_update_at=’ for #\u003cTicket:0x00005581f64e0a20\u003e\nDid you mean? last_contact_at=”}

if i would change a user

You might want to have a look at and verify your installed java version.

But I would try to update the elasticsearch plugin first and rebuild the searchindex:

sudo bin/elasticsearch-plugin remove ingest-attachment
sudo bin/elasticsearch-plugin install ingest-attachment
systemctl restart elasticsearch
zammad run rake searchindex:rebuild

This is not a zammad issue, sorry.

The error with java have i fix. the problem with elasticsearch not. I can not find Users or orginisations

i have install elasticsearch 6.x but the problem is not fixed

Elasticsearch 6.x is currently not supported by Zammad as far as I know (tried that some days ago).

Please do use elasticsearch 5.6.x.
You can take a look at this documentation page:

StatusCode: 500

{“error”:“undefined method `last_owner_update_at=’ for #\u003cTicket:0x00007fad403279f0\u003e\nDid you mean? last_contact_at=”}

after i Have install elasticsearch 5.6.x.

Where do you get this error message?

If I’m on tickets change status.

Sorry for the delay.
I assume that zammad already knows your elasticsearch URL.

Did you do a rebuild of the searchindex after reinstall?

zammad run rake searchindex:rebuild
