NetBox version

4.2.1

Topology Views version

4.2.0

Steps to Reproduce

Display topology

Expected Behavior

Topology to be displayed.

Observed Behavior

<class 'AttributeError'>

'CircuitTermination' object has no attribute 'provider_network'

Python version: 3.10.12
NetBox version: 4.2.1
Plugins:
netbox_ipcalculator: 1.4.9
netbox_lists: 4.0.1
netbox_topology_views: 4.2.0

Workaround is to untick "Show Circuit Terminations" for now.

How does your circuit look like? Both terminations on an interface?

The Z side is a provider network.

To circle back round to this comment #590 (comment)

netbox-topology-views/netbox_topology_views/views.py

Lines 446 to 453 in cf86419

	elif circuit_termination.provider_network is not None:
	if (
	circuit_termination.provider_network_id
	not in nodes_provider_networks
	):
	nodes_provider_networks[
	circuit_termination.provider_network.pk
	] = circuit_termination.provider_network

I think this should instead be:

 elif circuit_termination._provider_network is not None: 
     if ( 
         circuit_termination._provider_network_id 
         not in nodes_provider_networks 
     ): 
         nodes_provider_networks[ 
             circuit_termination._provider_network.pk 
         ] = circuit_termination._provider_network 

Saying that, I don't see nodes_provider_networks being referenced anywhere else, is this a half implemented feature (#454)?

After upgrading Netbox from 4.0.9 to 4.2.1 and Topology Views from 4.0.9 to 4.2.0
I am having the same error. I may have had the same error after the Netbox upgrade, but before updating Topology Views.

The same workaround @ibuclaw mentioned works for me.
No, only Z side of the circuit is terminated on an interface.

Circuit: "63.VLXP.931492..CBCL"
Termination side: A
Termination type: Circuits > Provider Network
Provider Network: "Internet"
Marked connected: False

Termination side: Z
Termination type: DCIM > Location
Provider Network: "Main Office"
Marked connected: False
Port speed: 80000
Upstream speed: 80000

Connection:

A side
Device: "MEN_deviceName_"
Interface: eth0

B Side
type: Circuit Termination
Circuit "63.VLXP.931492..CBCL"
Side: "63.VLXP.931492..CBCL: Termination Z"
Status: Connected

Below is a cable trace related to the Circuit.

Also and issue with all other termination types.
There is an error is the termination is not connected and the location, site, region is not empty.
