dynamicRequire Error when bundling with rollup

[prakattuladhar]

The following code in index.js causes files built using rollup to throw error during runtime.
(Error: Could not dynamically require "/build/reserved.js". ).

// index.js
var reservedMap = require(__dirname + '/reserved.js'); 

For now I've used dynamicRequireTargets with @rollup/plugin-commonjs plugin to resolve this issue.

plugins:[...,
commonjs({
      dynamicRequireTargets: ["node_modules/pg-format/lib/*.js"],
    })
],

Same issue when bundling with esbuild. Webpack seems to handle this gracefully, but most other bundlers either break during bundling or just leave the file out and break during runtime.

Anyone know of a workaround for esbuild?
