this error occurs when you use react-native bundle
use this react-native bundle --platform android --dev false --entry-file packages/mobile/index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

--entry-file is defined packages/mobile/index.js instead of index.js

the bundle is not recommended.

Try changing the path to index within MainApplication.java in packages/mobile/android/app/src/main/java/:

@Override
protected String getJSMainModuleName() {
    return "packages/mobile/index";
}

[hosseinmd]

Changing the index path is not the right way, because every platform has a different config in the index file.

@hosseinmd agree, but I also stumbled upon this problem and didn't find other solution. (react-native bundle didn't work)

[hosseinmd]

I think you have a problem in build.Gradle. Please check this.

project.ext.react = [
    entryFile: "packages/mobile/index.js",
    root: "../../../../",
]

@hosseinmd I made a small PR fixing this issue. Tested on android and ios emulators on macOS Catalina
