modules[moduleId] is undefined error is unhelpful

Do you want to request a feature or report a bug? FEATURE - error reporting

What is the current behavior? The webpack produces errorneous client code which pops modules[moduleId] is undefined error.

If the current behavior is a bug, please provide the steps to reproduce. Not sure. No matter what causes this error it should be human readable.

What is the expected behavior? The error should report whicvh module was not found or why. If this is a feature request, what is motivation or use case for changing the behavior? Software should be debugable. Please mention other relevant information such as the browser version, Node.js version, webpack version and Operating System.

I found a workaround thanks to @LukeOak :

optimization: { concatenateModules: false, providedExports: false, usedExports: false }

webpack 4.29.3

@trollkotze were you able to figure this out? I have tracked my issue to the same like as yours: modules[moduleId].call(module.exports, module, module.exports, __webpack_require__);
