Python subscribing to presence with detailedTelephonyState

Hi,

I am working in my sandboax environment to subscribe to incoming call to my extension. Since I later want to graduate this to looking at multiple extensions in the company I am looking at this event filter for my subscription:

/restapi/v1.0/account/~/extension/[extension_id]/presence

but since I am wanting to pull in detailed information about each individual call (specifically the session id) I am needing to scribe to the event with this filter:

/restapi/v1.0/account/~/extension/[extension_id]/presence?detailedTelephonyState=true

I can get the subscription to work when I don't filter to get the detailed information, but when I provide the detailedTelephonyState=true I get an error when receiving the notification. The error I get is "ValueError: Extra data:..."

How can I get my subscription to work and get the detailed telephony state?

The code I am using is:

def on_message(msg):
    print(msg)
    #PowerBI(msg)

def pubnub():
    s = sdk.create_subscription()
    s.add_events(['/restapi/v1.0/account/~/extension/[extension_id]/presence?detailedTelephonyState=true'])
    s.on(Events.notification, on_message)
    s.register()
    print(s.subscription())
    while True:
        sleep(0.1)

try:
    try:
        import Pubnub
        t = Thread(target=pubnub)
        t.start()
    except ImportError as e:
        print("No Pubnub SDK, skipping Pubnub test")

except KeyboardInterrupt:
    pass
pubnub()
