Error switching cable Type

[arthanson]

Deployment Type

Self-hosted

NetBox Version

v4.0.0-beta2

Python Version

3.8

Steps to Reproduce

1. Create a cable connecting some devices
2. Edit the cable and change the A side or B side Type in the dropdown

Expected Behavior

You should be able to change the cable type.

Observed Behavior

Potentially related to #15783, but doing the same as above on NetBox v3.7.8 does not reproduce the error, only seems to happen in beta.

Could you please assign it to me?

[arthanson]

@Julio-Oliveira-Encora actually, I'll take this one.

[Julio-Oliveira-Encora]
