demo.netbox.dev cable trace error

[devon-mar]

I was playing around with v3.0 on demo.netbox.dev and it seems that the cable trace button is broken for devices from netbox-demo-data. I didn't open an issue because I'm not sure if this has to do with NetBox or the demo data.

Steps to reproduce:

1. Open the interface tab on one of the demo devices (eg. dmi01-akron-sw01)
2. Click the blue cable trace button on one of the interfaces
3. The following error occurs

<class 'KeyError'>

35

Python version: 3.8.10
NetBox version: 3.0.1

I also can't delete the cable and recreate it as I get a unique constraint violation:

<class 'django.db.utils.IntegrityError'>

duplicate key value violates unique constraint "dcim_cablepath_origin_type_id_origin_id_41b6f814_uniq"
DETAIL:  Key (origin_type_id, origin_id)=(27, 171) already exists.


Python version: 3.8.10
NetBox version: 3.0.1
