netbox-proxbox: Error creating PVE node when there's existing Netbox device with the same name (duplicate)

I have set up the netbox-proxbox plugin following the setup guide in the README.MD

I also modified the models.py file to get it working with the newer netbox version

When I try to sync Proxmox to Netbox I get the following error:

<class 'AttributeError'>

'NoneType' object has no attribute 'name'

Python version: 3.10.6
NetBox version: 3.4.3

The stacktrace in the logs is as follows:

I do see some stuff being created in netbox like the Cluster (with the correct name) and the cluster type and tag so it seems the connection between the plugin, Netbox and Proxmox works. What could be causing this issue?

I seem to have found the reason the plugin is throwing the error. When setting up the devices to include the idrac interfaces and virtual bridges the plugin started crashing again.

Whenever I add an extra interface to one of the hosts that gets updated by proxbox the plugin fails. When I add an MTU to the interface it gets another error than the one we experienced above. Is adding extra interfaces to the proxbox nodes unsupported or is this a bug?

So after adding another interface (idrac) and giving it an MTU i get the following error:

Could you please open other issue to report this interface related problem?

Thank you for providing useful information, I will let this Issue open while I work on the defintive solution.

Have you created another device with the same name as the PVE’s? Like slc-app-02

Hello there!

I installed the plugin again (through git this time with the develop branch) and tested it again. I still get the same issue though. I have attached the log again below but it seems to be the exact same result as I got a while ago.

Thank you for testing, I will try to solve this and comeback to see if it works.
