Неправильно настроенная ошибка lookup_field в ``HyperlinkedModelSerializer``

Я сам Dhinesh. Но я новичок в Django Rest Framework. Здесь я пытаюсь изменить lookup_field из pk на пользовательское поле (IP_Address). Но я получаю эту ошибку снова и снова. Помогите решить эту проблему

Получение ImproperlyConfigured at /api/nodes/192.168.1.200/ Could not resolve URL for hyperlinked relationship using view name "nodemaster-detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field.

Models.py

class NodeMaster(models.Model):
    Device_Manufacturer = models.CharField(max_length=50, choices = MANUFACTURER)
    Device_Type = models.CharField(max_length=50, choices = DEVICE_TYPE)
    Physical_Location = models.CharField(max_length= 50, null= True)
    IP_Address =  models.CharField(max_length=50,unique = True )
    Community_String = models.CharField(max_length = 50, null = False)

    def __str__(self):
        return self.IP_Address

Serializers.py

class NodeSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = NodeMaster
        fields = '__all__'
        lookup_field = "IP_Address"

views.py

class NodeViewSet(viewsets.ModelViewSet):
    serializer_class = NodeSerializer
    queryset = NodeMaster.objects.all()
    lookup_field = "IP_Address"

urls.py

node_list = NodeViewSet.as_view({
    'get':'list',
    'post' : 'create'
})

node_detail = NodeViewSet.as_view({
    'get':'retrieve',
    'put' : 'update',
    'patch' : 'partial_update',
    'delete' : 'destroy'
})

urlpatterns = format_suffix_patterns([
    path('', node_list, name = 'nodemaster-list'),
    path('<str:IP_Address>/', node_detail, name='nodemaster-detail')
])
