Module vspheredb 1.8.0 doesnt work after upgrade icinga from 2.12.6 to 2.13.0

please reformat your post and/or remove chars that format your post.

and till then:
Good catch, vspheredb or incubator or icinga-php-legacy is not compatible with the current icinga-php-library

I couldn’t reproduce your issue but this endpoint produces this output:
/icingaweb2/vspheredb/configuration/servers

Fatal error
: Declaration of Evenement\EventEmitterTrait::on($event, callable $listener) must be compatible with ipl\Html\HtmlDocument::on($event, callable $listener): Icinga\Application\ClassLoader in
/usr/share/icinga-php/ipl/vendor/evenement/evenement/src/EventEmitterTrait.php
on line
28

and here is another one:

So If you rely on vspheredb you should not update at the moment

and vspheredb has less problems with icinga-php-legacy 1.0.4
so you can try and downgrade that package or wait for an update

the vspheredb module still works with
icingaweb2 2.12.6
Icinga PHP Library 0.18.1
if you use icingadb-web you need v1.3.1 instead of 1.4.0
