rpc get-subscribers returns no data using Tables/View

[ChrisHills463]

When trying to query subscribers using tables and view, no data is returned.

The script below gives the following output:-

There are 4 subscribers using dev.rpc.get_subscribers()
There are 0 subscribers using SubscriberTable()

Script:-

#!/usr/bin/python3

import yaml

from jnpr.junos import Device
from jnpr.junos.factory.factory_loader import FactoryLoader

subscriber_table = """
---
SubscriberTable:
    rpc: get-subscribers
    item: subscriber
    view: SubscriberView

SubscriberView:
    fields:
        interface: interface
        user_name: user-name
        logical_system: logical-system
        routing_instance: routing-instance
        stacked_vlan_id: stacked-vlan-id
        vlan_id: vlan-id
        ipv6_address: ipv6-address
"""

globals().update(
    FactoryLoader().load(yaml.load(subscriber_table, Loader=yaml.FullLoader))
)

HOST = "mx204-bng.lab"
dev = Device(host=HOST, port=22)
dev.open()

res = dev.rpc.get_subscribers()
subscribers = res.xpath('//subscriber')
print(f"There are {len(subscribers)} subscribers using dev.rpc.get_subscribers()")

res = SubscriberTable(dev)
res.get()
print(f"There are {len(res)} subscribers using SubscriberTable()")

dev.close()

This is the result of ssh mx204-bng.lab 'show subscribers | display xml':-
