Getting 'Unhandled error' when it tries to open control channel

[rucshah]

Hi,
Thanks for this great extension. I tried to configure this in my setup (JupyterServer + JupyterLab + Jupyter Enterprise Gateway) which is running in kubernetes. My setup has

jupyter_client          8.0.3
jupyter_core            5.2.0
jupyter-resource-usage  0.7.2
jupyter-server          1.23.42
jupyterhub              3.1.1
jupyterlab              3.5.2
jupyter_enterprise_gateway 3.1.0
ipykernel               6.21.1

But when extension makes a call, I see following exception in jupyter server:

   Traceback (most recent call last):
      File "/opt/conda/lib/python3.10/site-packages/tornado/web.py", line 1713, in _execute
        result = await result
      File "/opt/conda/lib/python3.10/site-packages/jupyter_resource_usage/api.py", line 115, in get
        control_channel = client.control_channel
      File "/opt/conda/lib/python3.10/site-packages/jupyter_server/gateway/managers.py", line 765, in control_channel
        assert self.channel_socket is not None
    AssertionError

Am I missing something here?

I encounter the same issue, maybe this extension not work with enterprise gateway?
