ckeditor_mentions error no new Ideas possible

[joshuamahr87]

Hi,

the installation works fine and the system runs fine except for the crucial task of creating Ideas and Challenges, the error states:

[Tue May 07 15:18:03.056476 2024] [php7:notice] [pid 898] [client 172.17.234.6:54085] Uncaught PHP Exception Drupal\Component\Plugin\Exception\PluginNotFoundException: "The "" plugin does not exist. Valid plugin IDs for Drupal\ckeditor_mentions\MentionsType\MentionsTypeManager are: node, user, realname" at /var/www/openidea/web/core/lib/Drupal/Component/Plugin/Discovery/DiscoveryTrait.php line 53, referer: https://10.44.67.10:9443/web/ideas

I've seen, that there have been multiple changes in die Version of ckeditor_mentions, but no versions works for me at this point. Is there an easy fix?

My system:

Ubuntu 22.04 (tested 20.04 as well)
PHP 7.4.33
MySQL 5.7
Composer 2.7.6 (tested a lot of version back to 2.1X)

Anyone an idea? The Plugins are installed, even the Update site mentions a possible update for this plugin.
