New 4.x menu: Systems fails

[moseisleydk]

In v4, there is a new menu item under Admin:

This fails:

Ive been upgrading fra v3.7-2.8.0 to v4.0-2.9.1 (Docker) and everything else seems (!) to work...

ok, removing this from configyration.py fixed the issue, but I need those validators:

`class UniqueSerial(CustomValidator):

def validate(self, instance):
    from dcim.models import Device

    if instance.serial and Device.objects.exclude(pk=instance.pk).filter(serial=instance.serial).exists():
        self.fail("The Serial number already exists in NetBox", field='serial')

class UniqueName(CustomValidator):

def validate(self, instance):
    from dcim.models import Device

    if instance.name and Device.objects.exclude(pk=instance.pk).filter(name=instance.name).exists():
        self.fail("The Device name already exists in NetBox", field='name')

class CheckSerialExists(CustomValidator):

def validate(self, instance):
    from dcim.models import Device

    if not instance.serial and instance.status!="planned" and instance.device_role.name not in ['Patch panel','Power Strip','Cable Manager','Shelf']:
        self.fail("Serial number must be on all Devices with Status different from Planned ", field='serial')

CUSTOM_VALIDATORS = {
'dcim.device': (
UniqueName(),CheckSerialExists(),UniqueSerial(),
)
}
`

This is the issue:

CUSTOM_VALIDATORS = { 'dcim.device': ( UniqueName(),CheckSerialExists(),UniqueSerial(), ) }

The problem seems to me to be that the /core/system/ page tries to handle the code validatorsa as an json object...
