Deployment Type

NetBox Cloud

NetBox Version

v3.7.3

Python Version

3.11

Steps to Reproduce

1. Create at least one module bay on a device
2. Install a module on that bay
3. Visit /api/dcim/module-bays/
4. Visit /api/dcim/module-bays/?brief=true

Expected Behavior

The serialized representation of the module bay should include an installed_module field in both responses, with a representation of the installed module.

Observed Behavior

The installed_module field is absent when brief mode is enabled. There is instead an empty module field.
