Cant look at IP Addresses in a Prefix

[sebedh]

The following error is returned when trying to look at IP addresses in one of our Prefixes:
'NoneType' object has no attribute 'get_absolute_url'

I have tried to run the IP Address Fix script located https://github.com/netbox-community/customizations/blob/master/scripts/fix_assigned_ips.py.

The script runs successfully and it did seem to find some ip addresses. However it still does not work. Any ideas?

Running Netbox v3.5.3

I actually found the problem my self.
I had IP addresses in that prefix that had assigned_object_id == 0. Which broke the view. Not sure how that happened. Nothing in the change log...
I fixed it by running this in the nbshell

>>> for ip in prefix.get_child_ips():
...     if ip.assigned_object_id == 0:
...             print(f"ip has 0 assigned as id: {ip.address}")
...

I went to that ip address url, clicked edit and save.
