Uncaught ReferenceError: process is not defined, won't build in Webpack

I tried building this in my project with latest webpack and got the following error:

Uncaught ReferenceError: process is not defined,

Seems like webpack is hitting a require('util/') and bundling Node.js's implementation of util, which has Node.js only code, hence the error above.

I stripped it down to a simple test case.

webpack.config.js

const path = require('path');

module.exports = {
  mode : "development",
  entry : { main: "./entry.js" },
  output : {
    path : path.resolve(__dirname, "dist"),
    filename : "[name].js",
    library : "datadesk",
    libraryTarget : "umd"
  },
  resolve: {
    fallback: {
      assert: require.resolve("assert"),
    }
  },
  devtool: "source-map"
};

entry.js

const a = require('assert');

package.json

{
  "name": "testtt",
  "version": "1.0.0",
  "dependencies": {
    "assert": "^2.0.0",
    "webpack": "^5.65.0"
  },
  "devDependencies": {
    "webpack-cli": "^4.9.1"
  }
}

testtt.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <script src="./dist/main.js"></script>
  </head>
  <body>
  </body>
</html>

Also here's the built files. You can copy and run something like python -m http.server to open, or another small http file server.

I think this can be worked around by also polyfilling util in the webpack config, but there is no util-browserify package that I've found yet on npm
