Web socket failure with the jupyter-ai chat api in LTJH

[JuanMoranAdarraga]

Bug description

Inmediately after an installation of LTJH in Azure following the "Deploy to Azure button", when I install jupyter_ai extension in jupyter hub, the chat interface fails and the browser debugger keeps showing:

WebSocket connection to 'wss://jupyterhub.domainname.com/user/adminuser/api/ai/chats' failed:

Expected behaviour

The chat interface should show a message like this:

Welcome to Jupyter AI! To get started, please select a language model to chat with from the settings panel. You may also need to provide API credentials, so have those handy.

The message shown is this:

There seems to be a problem with the Chat backend, please look at the JupyterLab server logs or contact your administrator to correct this problem.

How to reproduce

I have tried many combinations of versions and it always fails. I think that this extension that works perfectly in a single user environment always fails in LTJH. To reproduce just install LTJH and try to install the extension.

Your personal set up

I am using the LTJH with the automatic configuration from "Deploy to Azure button" that is recommended in the documentation.

@JuanMoranAdarraga What's the version of JupyterLab and JupyterAI are you using? The new JupyterAI release requires JupyterLab 4.0+
