Thank you so much for helping improve the quality of Dash!

Describe your context

We are hosting jupyterlab on eks cluster with jupyterhub integration for the analytical purposes. In our lab environment we have python kernel with all necessary visualization libs. Dash was working fine previously with separate jupyter-dash installation but now its not working.

Based on the documentation we followed this step

replace the result of pip list | grep dash below

Describe the bug

Based on the investigation probably this function is causing the issue.here. I run this code blocked yesterday and its still running in my remote sandbox. As mentioned earlier its hosted on eks pod.

from dash import Dash, html, dcc
import plotly.express as px
import pandas as pd

from dash import jupyter_dash
jupyter_dash.infer_jupyter_proxy_config()

Expected behavior

jupyter_dash.infer_jupyter_proxy_config() should infer the proxy config and let the dash render the plots inline.

Screenshots

If applicable, add screenshots or screen recording to help explain your problem.
