NoneType' object has no attribute 'items'

[mkarel]

All, I am working to move some devices within a branch and when with some devices I have been getting the error message below when saving my change on the device. Has anyone seen this error message before? any detailed logging I can enable to trace what might be triggering this?

The device does have device bays and children populated. and wonder if that may be part of the issue

<class 'AttributeError'>

'NoneType' object has no attribute 'items'

Python version: 3.10.12
NetBox version: 4.2.6
Plugins:
netbox_branching: 0.5.4

I did some testing it looks like has something to do with having a Tag on the child device.

Hi! I don’t have a direct answer to your issue, but maybe this helps as a starting point.

Here’s the link to the NetBox documentation on configuring logging:
https://netboxlabs.com/docs/netbox/en/stable/configuration/system/#logging

If that doesn’t surface enough details, enabling DEBUG mode might be useful as a next step:
https://netboxlabs.com/docs/netbox/en/stable/configuration/development/#debug

Hopefully this helps to get a bit more insight into what’s going on.

Thanks @pheus for the info. I will look to get logging setup and see if I can capture some logs. Tags definitely don't look to behave right in a branch and looks to be a bug of some sort.
