Netbox crashing after updating.

[ITTV-tools]

When I open the config render of a device. Netbox is crashing.
How to debug this ?

<class 'TypeError'>

argument of type 'NoneType' is not iterable

Python version: 3.12.3
NetBox version: 4.2.1
Plugins:
netbox_interface_synchronization: 4.1.4
netbox_reorder_rack: 1.1.3
netbox_topology_views: 4.2.0

Console:
2025/01/16 09:49:01 [info] 452#452 OpenSSL 3.0.13 30 Jan 2024, 300000d0

2025/01/16 09:49:01 [notice] 426#426 app process 427 exited with code 0

2025/01/16 09:49:01 [notice] 7#7 process 426 exited with code 0

I use Netbox Docker Container

I updated from 4.1.7 to 4.2.1

Debug Mode says there is an issue with my template: , line 226, in top-level template code.
Line:
{%- elif "tagged-all" in interface.mode %}

I guess this should not crash the whole system

I am getting the same issue with interface.mode, did you get a solution ?

Solution: Change {%- elif "tagged-all" in interface.mode %} to {%- elif interface.mode == "tagged-all" %}
