[Python] disconnect message in python when closing waapi connection (wamp, autobahn)

With the code from the official website:
https://www.audiokinetic.com/en/library/2024.1.5_8803/?source=SDK&id=waapi_client_python_rpc.html

from waapi import WaapiClient, CannotConnectToWaapiException
from pprint import pprint

try:
# Connecting to Waapi using default URL
with WaapiClient() as client:
# NOTE: client will automatically disconnect at the end of the scope

# == Simple RPC without argument
print("Getting Wwise instance information:")
result = client.call("ak.wwise.core.getInfo")
pprint(result)

# == RPC with arguments
print("Query the Default Work Unit information:")
object_get_args = {
"from": {
"path": ["\\Actor-Mixer Hierarchy\\Default Work Unit"]
},
"options": {
"return": ["id", "name", "type"]
}
}
result = client.call("ak.wwise.core.object.get", object_get_args)
pprint(result)
except CannotConnectToWaapiException:
print("Could not connect to Waapi: Is Wwise running and Wwise Authoring API enabled?")


And here’s my custom code that handles the connection and disconnect:

from waapi import WaapiClient, CannotConnectToWaapiException

class WwiseConnector:
def __init__(self):
self.client = None

def connect(self):
try:
self.client = WaapiClient()
except CannotConnectToWaapiException:
print("Cannot connect to WAAPI — is Wwise open with WAAPI enabled?")
except Exception as e:
print(f"Unexpected error: {e}")

def disconnect(self):
if self.client:
self.client.disconnect()
self.client = None


However, I keep getting the following error:

session closed with reason wamp.close.transport_lost [WAMP transport was lost without closing the session]
​

Any idea why this is happening, and what’s the correct way to manage the WAAPI connection and disconnection lifecycle?
