I’m developing an app that so far has worked well and I haven’t touched it for 2 days and now as soon as I tried to make it work it stopped working and it gives me this error I don’t know what happened: I also tried to create a new one project and re-enter the codes but it always gives me this cursed error: iOS Bundling complete 76ms

ERROR TypeError: Cannot read property ‘array’ of undefined, js engine: hermes

ERROR Invariant Violation: "main" has not been registered. This can happen if:

  • Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
  • A module failed to load due to an error and AppRegistry.registerComponent wasn’t called., js engine: hermes

  1. Chosen as BEST ANSWER

    I finally solved it by cleaning the cache but not only did I have to remove some deprecations


  2. Whenever I hit this error, often what works for me is to just restart everything and clear my cache.

    1. Stop Metro
    2. Uninstall the app from device/simulator
    3. Restart Metro with yarn start --reset-cache. Though in your case it would be expo start -c
    4. Rebuild the app
