404 error for Create & Add Another (Contact Assignment)

[Azmodeszer]

Deployment Type

Self-hosted

NetBox Version

4.0.6

Python Version

3.11

Steps to Reproduce

1. Create a site
2. Create a contact
3. From the site's Contacts tab, click Add a contact
4. Choose the contact
5. Click "Create & Add Another "

Expected Behavior

Assignment is added and you're redirected to the same form for another.

Observed Behavior

Object is created, but an error shows up:

 /tenancy/contact-assignments/add/
The requested page does not exist

Same as #7757?

(Seems to impact contact assignments to all object types, not just sites.)

Thanks for reporting a problem you've encountered in NetBox. With a little work I've managed to reproduce the problem in a fresh installation of NetBox v4.0.6 (I updated the issue body to fill in the gaps).
Thanks for your interest in improving NetBox!

I've moved this issue to needs owner status. If you're interested in working it through to a PR, please leave a comment to that effect and a maintainer will assign it to you for implementation. Otherwise, another developer with the necessary skills and capacity can pick it up.
