Webpack Error: Cannot find module 'node:process'

I'm trying to bundle a Node script so users don't have to run npm install before using it.

npx webpack runs fine and without warnings, but node dist/main.js gives the following error: Error: Cannot find module 'node:process'.

If I edit dist/main.js and comment out the line about node:process, the bundled script seems to run just fine.

Here's my webpack config:

export default {
  target: 'node',
  mode: 'development',
  output: {
    module: true,
    chunkFormat: 'module',
    filename: 'main.js'
  },
  experiments: {
    topLevelAwait: true,
    outputModule: true
  }
};
