Missing pre-change data for device bay

[blipnet]

NetBox Version: v3.3.10
Python Version: 3.8.6

When updating device bays by adding or removing a device from the bay the pre-change data is missing.

In WebGUI there is following warning: Warning: Comparing non-atomic change to previous change record
REST API: prechange_data is null
Webhook: snapshot -> prechange is null

There is same behavior both when adding or removing a device.

I'm working with webhooks to update our asset management system, when someone change the device in a device bay this needs to be updated.

So when someone removes a device from device bay the webhook snapshot is (it's the same in REST API):
"snapshots": {
"prechange": null,
"postchange": {
"created": "2021-06-29T00:00:00Z",
"last_updated": "2023-01-05T11:39:15.498Z",
"device": 4761,
"name": "6",
"label": "Blade 6",
"description": "",
"installed_device": null,
"custom_fields": {},
"tags": []
}
}

Shouldn't the previous installed device be in prechange?
I do get this behavior when installing a device in device bay but not when removing.

I don't know if this is a bug or if I don't understand how to retrieve the data

That's a bug, DeviceBayPopulateView and DeviceBayDepopulateView doesn't call snapshot before disassociating the device. Please create an issue with the required replication steps.
