Exception while installing ipfabric_netbox Plugin

[thomaspries]

• NetBox 4.3.7
• Python: 3.12.7
• Django 5.2.5
• Postgres 16.9
• ipfabric_netbox 4.2.2

I installed the netbox-branching plugin without any issues, and continued with the ipfabric plugin, but at the (venv) $ python3 manage.py migrate I get an exception:

(venv) root@checkmk:/opt/netbox/netbox#  python3 manage.py migrate

This can happen if you are inheriting models from an app with migrations (e.g. contrib.auth)
 in an app with no migrations; see https://docs.djangoproject.com/en/5.2/topics/migrations/#dependencies for more

Any help is highly appreciated.
