Mass edit is not working for some IP addresses due to `assigned_object` validation

• Python version: 3.10
• Nautobot version: 1.3.2 (tested & failed also with 1.2.11)

Steps to Reproduce

1. Select at least two IP addresses (don’t know how to more properly identify “problematic” addresses from GUI because for some it works without error)
2. Choose “Edit selected” in order to mass edit multiple objects
3. Modify objects (probably anyhow) (I tried to add a tag or add a comment)

Expected Behavior

Objects should be updated without any errors.

Observed Behavior

Saving failed with an error related to assigned_object_type and assigned_object_id. But when I edit the very same objects individually the save is successful without any issues! This is a strange difference between validation happening upon saving a single address vs bulk save of multiple addresses.

Maybe the issue could be also related to this PR: https://github.com/nautobot/nautobot/pull/1592 ? (I tried just a simple & quick search based on keywords from error message)

btw. Your demo nautobot instance is not working (can’t login either with demo credentials) so I couldn’t test it and provide links from your environment.

Closing as resolved. Found the root case and a way how to fix it. Thanks for the support 😃

@ubajze After some digging we found that DB inconsistencies was created during our migration from Netbox to Nautobot.

This issue can be closed now, thanks for support 👍
