Python Version

Steps to Reproduce

This is actually an issue with NetBox Cloud v4.5.1.
Sorry if this is not the right channel to communicate NetBox Cloud errors - I'm just a free user.

I notice a random issue when playing around with NetBox Cloud - using it to map my homelab.

I created a simple Cluster:

Name: Main
Type: Proxmox
Status: Active
Scope: Home (Location)

When I try to associate an existing device to it, I get the following server error (markdown mockup, content is verbatim):

Caution

Server Error

There was a problem with your request. Please contact an administrator.

The complete exception is provided below:
<class 'KeyError'>

'location'

Python version: 3.12.3
NetBox version: 4.5.1
Plugins: 
  nbc_auth_extensions: 1.20.2
  nbc_eventsink_extensions: 1.8.4
  nbc_requestmetric_extensions: 1.10.1
  nbce_common: 2.0.6
  netbox_branching: 0.8.1
  netbox_changes: 0.4.3
  netbox_labs_console: 2.0.0
The request which yielded the above error is shown below:
POST https://ghet3177.cloud.netboxapp.com/dcim/devices/11/edit/?return_url=/dcim/devices/
If further assistance is required, please post to the NetBox discussion forum on GitHub.

To be clear, in spite of the "location" KeyError, issue does not seem to be related to Locations at all.

Expected Behavior

It should be possible to associate devices to a cluster using NetBox Cloud v4.5.1

Observed Behavior

A system error was raised in that case.
