Channels: undefined index: config

[oxzi]

The following was reported in the Community forum, https://community.icinga.com/t/current-state-of-icinga-notifications-modules/14666.

When I try to create one, I get an “undefined index: config” error, regardless of which type I select.

In the Notifications tab under Events, I get the following SQLSTATE error:
syntax error or access violation: 1305 FUNCTION notifications.json_objectagg does not exist

This was addressed by updating the MariaDB daemon to 10.5.27.

However, the first error still remains:

On the ‘Add Channel’ screen, I get a red message saying ‘Undefined index: config’ above the Name field when I click the ‘Add Channel’ button, regardless of which type I choose

A bit more information is available in the linked forum thread.
