Bundling fails on 2.21.0

Bug description

After upgrading to 2.21.0 and running ESBuild to bundle, a new error occurs:

> ../../common/temp/node_modules/.pnpm/@prisma+client@2.21.0_prisma@2.21.0/node_modules/@prisma/client/runtime/index.js:24152:23: 
error: Could not resolve "_http_common" (mark it as external to exclude it from the bundle)
24152 │   var common = require("_http_common");

and

"var runtimeRequire = 
  typeof __webpack_require__ === 'function' ? 
     __non_webpack_require__ : require // eslint-disable-line"

How to reproduce

1. Install Prisma and ESBuild using PNPM.
2. Run prisma generate
3. Run esbuild app.js --bundle --platform=node --target=node14
4. See error

Expected behavior

Prior to 2.21.0 bundling was successful.

With webpack 5, simply adding '_http_common' to an array in the externals build option wasn’t enough for me, I had to specify it this way:

{
  // ...
  externals: {
    "_http_common": "commonjs2 _http_common",
  }
}

In your webpack.config.js, add externals: ['_http_common', 'encoding'],
