Regression 1.7.3 to 1.7.4: __nccwpck_require__ is not defined

[vieira]

After updating from @vercel/webpack-asset-relocator-loader 1.7.3 to 1.7.4 the build still succeeds but the generated bundle now fails to start with the following error:

/Users/.../dist/index.js:198193
const googleProtoFilesDir = __nccwpck_require__.ab + "protos";
                            ^

Relevant webpack configuration:

const webpack = require('webpack');

module.exports = {
  entry: './index.js',
  target: 'node20',
  node: false,
  devtool: false,
  resolve: {
    mainFields: ['main', 'module'],
  },
  // ...
  optimization: {
    minimize: false,
  },
  module: {
    rules: [
      {
        test: /\.mjs$/,
        type: 'javascript/auto',
      },
      {
        test: /\.m?js?$/,
        exclude: /node_modules/,
        use: {
          loader: 'babel-loader',
          options: { rootMode: 'upward' },
        },
      },
      {
        test: /\.(m?js|node)$/,
        parser: { amd: false },
        use: {
          loader: '@vercel/webpack-asset-relocator-loader',
          options: {},
        },
      },
    ],
  },
  stats: {
    warnings: false,
  },
}

Downgrading to 1.7.3 fixes the issue, without any other changes.

This might be related to the upgrade to ncc. I was surprised to find it there because we have a circular dependency:

• webpack-asset-relocator-loader depends on ncc
• ncc depends on webpack-asset-relocator-loader

I was forced to upgrade ncc in this repo since it was using a really old version that didn't support newer Node.js versions.

• https://github.com/vercel/webpack-asset-relocator-loader/pull/187

@guybedford Do you recall why ncc is needed? Can we drop it?
