Cannot edit device

Help
#1

Hello,
This morning I wanted to rename one of my devices in LibreNMS, unfortunately I can’t do it, when I click on the edit button I’ve got an error message which says “Oops something went wrong”, check the attachment.

Steps to reproduce an issue - Click on edit device button.
The output of ./validate.php - Here is it:
