Add Device Error and No Graph data

[David_B]

I did a fresh install of LibreNMS on Oracle Linux 8 (Centos8) and using PHP 7.4 (instead of 7.3) following the instructions at (https://www.centlinux.com/2021/02/install-librenms-network-monitoring-tool-centos-8.html)

./validate.php shows everything looking good:

When I add a device I receive the error: Missing required parameter for [Route: device] [URI: device/{device}/{tab?}/{vars?}] [Missing parameter: device].

The device is added and SNMPP information is populated - CPU, Interfaces, etc.
Graphs are created, but contain no data.

Any help is greatly appreciated!

Update:

Did a clean install with PHP 7.3, still get the error when adding a device:
[Route: device] [URI: device/{device}/{tab?}/{vars?}] [Missing parameter: device].

Polling is working, graphs are generating, and they contain data
