Summary: Motivation: `Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication).` is an error that happens rarely, and most SO answers end up recommending to use `react-native bundle` to work around. I stumbled upon this error the other day and it took me a while to figure out that the error was caused by the fact that my `entryFile` path was pointing to an existing but invalid file. I figured it would be nice to mention this because I believe this will be a frequent cause of the error. ## Changelog <!-- Help reviewers and the release process by writing your own changelog entry.
