PHP exceptions and broken graphs

Help
1

Good morning and wish a good month.

I have the following problem running validate.php from terminal and i believe it is part of a bigger problem in all LibreNMS WebUI.
I see several PHP errors in many sub-pages in the WebUI and whatever i tryed i haven’t figure it out.

I am using Librenms with Ubuntu 22.04 latest update in both OS and Application and navigating through Firefox 110.0(64bit).

  1. From Services Page:

“Exception: Undefined variable $stype”
“/opt/librenms/includes/html/modal/new_service.inc.php:23”
Services »
“Exception: Undefined array key “view””
“/opt/librenms/includes/html/pages/services.inc.php:34”
“Exception: Undefined array key “state””
“/opt/librenms/includes/html/pages/services.inc.php:45”
“Exception: Undefined variable $where”
“/opt/librenms/includes/html/pages/services.inc.php:150”

2)From Validate.php
librenms@librenms:~$ ./validate.php

None of the graphs are working, but I don’t see any errors on the WebUI
