Notification UUID/PK Triggering Error

Describe the bug*

I'm trying to get a notification to trigger from a plugin that I'm writing:

from common.notifications import trigger_notification
from django.contrib.auth import get_user_model
from machine.models import MachineConfig

class Notifications:

    def test_notification(machine):

        User = get_user_model()

        user = User.objects.filter(is_superuser=True)

        machine = MachineConfig.objects.get(pk=machine.pk)

        trigger_notification(
            obj=machine,
            category="system",
            targets=user,
            context={
                "name": "Test",
                "message": "Hello world",
            },
            check_recent=False,
        )

But I'm getting an error (trace in the Issue Log Output Field) when this method is called.

If I set obj=None, the notification triggers (however I get an error about it being Null and when I click on the notification, InvenTree obviously doesn't know where to navigate to).

I believe it has something to do with the fact that the MachineConfig class uses a UUID as an id (id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)), and the NotificationMessage is then trying to cast this to an int (target_object_id = models.PositiveIntegerField()).

Am I providing the wrong obj value here or is something else going wrong?

Thanks,
James.

Steps to Reproduce

Call trigger_notification where obj is passed a MachineConfig instance.

Expected behaviour

The notification is visible within the UI and the error does not occur.

Deployment Method

Docker
