RHL breaks important information from React

[kud]

Description

What you are reporting: some error information is missing when RHL is enabled.

I recently had a problem. I forgot to export default a component I imported into another one.

And the errors from the console were not so explicit due to RHL.

Expected behavior

What you think should happen: when I disable RHL, I've got this kind of errors which helps me a lot:

 Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of `Element`.

or also:

Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of `Element`.

Actual behavior

What actually happens: when I enable RHL, I've got those errors:

TypeError: "undefined has no properties" in backend.js

or again:

TypeError: undefined has no properties react-hot-loader.development.js:1229

which is way less clear.

Environment

React Hot Loader version: 4.12.11

Run these commands in the project folder and fill in their results:

1. node -v: v12.9.0
2. npm -v: 6.11.1

Then, specify:

1. Operating system: macOS 10.14.6
2. Browser and version: Firefox 70.0a1 (2019-08-21) (64-bit)

Reproducible Demo

I'm sorry, I cannot yet.
