При добавлении групп с разрешением от Django панели администратора, а также при добавлении других отношений M2M. Я получил эту ошибку !!

Он говорит: TypeError: _bulk_create () получил неожиданный аргумент ключевого слова ignore_conflicts

Я не могу найти ошибку, вероятно, ошибка noob. 

class GroupSerializer(serializers.ModelSerializer):
    permissions = PermissionSerializerGroup(many=True, required=False)

    class Meta:
        model = Group
        fields = ('id', 'name', 'permissions')
        extra_kwargs = {
            'name': {'validators': []},
        }

    def create(self, validated_data):
        print(validated_data)
        permissions_data = validated_data.pop("permissions")
        obj, group = Group.objects.update_or_create(name=validated_data["name"])
        obj.permissions.clear()
        for permission in permissions_data:
            per = Permission.objects.get(codename=permission["codename"])
            obj.permissions.add(per)
        obj.save()
        return obj

Я решил эту проблему, понизив версию Django до 2.2.12 Похоже, что Django v3.0 + имеет эту проблему
