Hello,

I am struggling to get one of the ipywidget examples (web3) working and would be very grateful for some help. I’d like to get a minimal example running which involves displaying widgets in a webpage and communicating with a notebook server.

# Environment:

ipywidget v8.0.2  
MacOS v12.6.1 (Apple M1)  
conda 22.9.0  
Python 3.7.13  
Google Chrome Version 107.0.5304.87 (Official Build) (arm64)  
Firefox 106.0.3 (64-bit)

# Steps to recreate

1. create and activate a new conda environment
2. clone ipywidgets
3. follow the setup instructions for the example “web3” [ipywidgets/examples/web3 at main · jupyter-widgets/ipywidgets · GitHub](https://github.com/jupyter-widgets/ipywidgets/tree/master/examples/web3#try-it)
4. try opening the webpage in both firefox and chrome

Additionally, I have tried `git checkout tags/8.0.2` immediately after cloning the repo without effect.

# Expected result

Some visual indication of success in the webpage.

# Actual result

Only a blank webpage appears.

In the Firefox developer console, this error is reported:

```auto
Uncaught (in promise) ReferenceError: process is not defined
    makeSettings serverconnection.js:156
    makeSettings serverconnection.js:53
    <anonymous> index.js:15
    EventListener.handleEvent* index.js:13
    <anonymous> index.built.js:244441

serverconnection.js:156
    <anonymous> index.js:38
    (Async: EventListener.handleEvent)
    <anonymous> index.js:13

```

Please let me know if there is any other info I should add. Many thanks for any help.  
Andy
