repack: Can't find variable: __webpack_require__

Environment

React Native: 0.69.7 Repack: 3.0.0 Webpack: 5.75.0 OS: Windows10 64bit

Description

I create an demo to learn repack and followed the docs to configure the demo. everything works fine until I configured the code-splitting section. It starts to report error like below:

ERROR ReferenceError: Can’t find variable: webpack_require ERROR Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication). A frequent cause of the error is that the application entry file path is incorrect. This can also happen when the JS bundle is corrupt or there is an early initialization error when loading React Native.

Looks like we’re trying to tackle to many problems at the same time.

@namdao Please open a new issue. Since you are using Module Federation instead of async-chunks, the root cause of your problems might be completely different. Please add a repro repo with you code there as well, it helps a lot with investigating these kind of issues. Also, please add info about the platform you’re having issues on, the build variant (Release, Debug) and the platform you are working on (Mac, Linux, Windows). From your screenshot it looks like Release iOS, but please add that info so we’re on the same page.

@chj-damon I run your repackDemo codebase and after:

adding bundle-command to Bundle React Native code and images like the docs suggest
using an url pointing to existing localhost server serving bundles in the ScriptManager config

Here’s the complete diff. The most important files are ios/repackDemo.xcodeproj/project.pbxproj and index.js

I was able to build and run:

the iOS app in both Debug (with devServer) and Release (with localhost server serving student.chunk.bundle and teacher.chunk.bundle)
the Android app in Debug variant

Currently I’m not able to run the Android in Release variant, the app crashes instantly after opening. I’m going to investigate it on 9th of January.

Please specify your environment info as well (the platform you’re having issues on, the build variant (Release, Debug) and the platform you are working on (Mac, Linux, Windows), thanks!
