我正在尝试使用 django-graphene 返回过滤结果，但它给出了有关错误消息的错误

class PatientType(DjangoObjectType):
    class Meta:
        model = Patients
        exclude = ('active',)
        interfaces = (relay.Node,)


class PatientsQuery(ObjectType):
    get_patient = graphene.Field(PatientType, id=graphene.Int())
    all_patients = graphene.List(
        PatientType, first=graphene.Int(), skip=graphene.Int(), phone_no=graphene.Int()
    )
    upcoming_appointments = DjangoFilterConnectionField(PatientType)


@permissions_checker([IsAuthenticated, CheckIsOrganizationActive])
def resolve_upcoming_appointments(self, info, **kwargs) -> List:
    d = datetime.today() - timedelta(hours=1)
    settings.TIME_ZONE  # 'Asia/Karachi'
    aware_datetime = make_aware(d)
    res = Patients.objects.filter(appointments__booking_date__gte=aware_datetime,
                                  appointments__booking_date__day=aware_datetime.day,
                                  appointments__status=True)
    if res:
        return res
    return []


class Query(
    organization_schema.OrganizationQuery,
    inventory_schema.MedicineQuery,
    patient_schema.PatientsQuery,
    graphene.ObjectType,
):
    pass
