React-native: Upgrade to 0.50.1 - Bundling `index.js` error: bundling failed: Error of metro-bundler

[oriharel]

Because of issue #16737 I had to do a workaround (which I'm still not sure works) of saving a backup copy of the pre-upgrade xcodeproj file and pasting it again after upgrading. Now the project loads on XCode, but I can't run the app. I get this error in the packager:

Loading dependency graph, done.
Bundling `index.js`  [development, non-minified]  0.0% (0/1), failed.

@oriharel You should compile your index.android.js & index.ios.js to index.js

Same issue. I only have index.js.

[hmenzagh]

Same here, I'm sure there is a good reason but I don't get it

[fpyang]

I fix the issue by following @chocky335's comment

Same issue even after changing index.ios.js to index.js

[jrumbut]

My project had an edited AppDelegate.m file and I needed to change the line that looked like (though in my case not exactly like)

jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];

to reflect the change to index.js instead of index.ios.js. Hope that helps someone!
