I had the same problem with ARP table.
removed “?int” from line 60 in /opt/librenms/LibreNMS/Cache/Device.php
“public function get(?int $device_id) : \App\Models\Device”
I know it’s not the right fix but i needed this to work “asap” 
This also worked for me … even if don’t now what this change actually does 
Thx
Looks like it might of broke after https://github.com/librenms/librenms/pull/11975, as that was on 7/31, and added the changes you removed to fix the issue.

I made this change locally but still got same error.
do I need to somehow flush the cache?
I’ve tested on 2 different systems, both work.
whats the output of git diff after you apply the patch?
also, could you post the whole error in that case?
you are right, doing ./scripts/github-apply 12075 helped
