'CircuitTermination' object has no attribute 'name'

Environment

• Python version: “3.7.3”
• NetBox version: “2.10.3”

Steps to Reproduce

On the API, in the page 3 i have this error 500:

"Got AttributeError when attempting to get a value for field `name` on serializer `NestedInterfaceSerializer`.\nThe serializer field might be named incorrectly and not match any attribute or key on the `CircuitTermination` instance.\nOriginal exception text was: 'CircuitTermination' object has no attribute 'name'."

URL called is : https://netbox/api/circuits/circuits/?cf_technology=VDSL&offset=100&type=s-internet-over-best-effort-line

I have 167 circuits that match my search. Only part 100 - 150 does not work.

This URL works :

Thank you @Hedius for taking the time to provide a detailed reproduction script per the issue template. Using the information you provided, I was able to replicate the reported bug, and can now work on fixing it.

Environment

• Python version: “3.9.1” (also happens on 3.7)
• NetBox version: “2.10.3”

Hello. Clean/Empty installation. Maybe less steps are needed, but our setup for this issue looks exactly like this.

Steps to Reproduce

1. Create Provider1

2. Create Provider2

3. Create Tenant1

4. Create Tenant2

5. Create Site1

6. Create Device Role: Cable Management

7. Create Manufacturer1

8. Create Device Type: housing-panel – Manufacturer1 – Height 1U

9. Create Device Tray1 – Role: Cable Management – Device Type: housing-panel – Site: Site1 – Tenant: Tenant1

10. Add a rear port: Rear Port 1 – Type: LC/APC

11. Add a front port: Front Port 1 – Type: LC/APC – Assign the rear port

12. Create a Circuit Type: CircuitType1

13. Add Circuit1 – Provider: Provider1 – Type: CircuitType1 – Tenant: Tenant1

14. Add Circuit2 – Provider: Provider2 – Type: CircuitType1 – Tenant: Tenant2

15. Add a Z side to Circuit1 – Site: Site1 – 100Gbps up/down

16. Add a Z side to Circuit2 – Site: Site1 – 100Gbps up/down

17. Cable the Z side of Circuit1 to the device tray1 (Front Port 1)

18. Cable the Z side of Circuit2 to the device tray1 (Rear Port 1)

The setup should look like this:

Expected Behavior

The following queries should not fail: /api/circuits/circuits/2/ /api/circuits/circuits/1/ /api/circuits/circuits/

Observed Behavior

After doing this, opening both circuits via the API will fail: {"error": "Got AttributeError when attempting to get a value for field `name` on serializer `NestedInterfaceSerializer`.\nThe serializer field might be named incorrectly and not match any attribute or key on the `CircuitTermination` instance.\nOriginal exception text was: 'CircuitTermination' object has no attribute 'name'.", "exception": "AttributeError", "netbox_version": "2.10.3", "python_version": "3.9.1"}

Queries that will fail: /api/circuits/circuits/2/ /api/circuits/circuits/1/ /api/circuits/circuits/

Conclusion

The problem is caused by the cables (maybe). Removing a cable will fix the problem for the now unplugged circuit.
