@PetrVoronov , I'm not able to reproduce this with the steps you listed. You listed your NetBox version as 4.2.8, but then your error output shows 4.2.2. Please try this against 4.2.8 to make sure it hasn't already been fixed.

Also, since step #2 was vague, I assumed you meant the IP Address list view at /ipam/ip-addresses/. Is that correct? If so, then I cannot reproduce as it works for me on main and 4.2.8. If not, then please let me know which page you mean in step #2.

@jnovinger Sorry, fixed, version 4.2.2 I've added last one because I've see the same lines of code in source of 4.2.8. I've fixed it using this line:
```    linkify=lambda record: record.assigned_object.get_absolute_url() if record.assigned_object else None,```
on my test env of 4.2.2, I also can't reproduce it on demo.netbox. But I will try to find route cause on my dataset.

@jnovinger I've found error and it related only to my dataset, some how I have assigned object id, but without object -

    "assigned_object_type": null,
    "assigned_object_id": 11321,
    "assigned_object": null,

I've checked my db from previous setup with 3.1.7 and for this ip there is no assigned_object_id, so looks like it was some migration bug.

I don't think that I will reproduce all and find mistake in migration scripts.
