How to debug Production app that crashes immediately?

Hello there!

First time here.

I have an app that’s been working perfectly fine in Expo Go and simulator.

Once I built it using EAS build and submitted to app store, both the Android and iOS version of the app crashes immediately upon opening.

I couldn’t get sentry working somewhere along the same issue here : Unable to send test event to Sentry from React Native using Expo · Issue #294 · expo/sentry-expo · GitHub

Any help would be appreciated. Thanks!

Hi @jantzen

Start with this page: Debugging - Expo Documentation

in particular the part that says:

Hint: Sometimes, running your app in “production mode” locally will show errors that normally wouldn’t be thrown. You can run an app locally in production by running npx expo start --no-dev --minify. “–no-dev” tells the server not to be run in development mode, and “–minify” will minify your code the same way it is for production JavaScript bundles.

Thanks for your reply.

I’ve done this too. It runs perfectly fine.

Try the other stuff on that page as well.

Also, see if the device logs give you anything.

If that doesn’t help, try this: fyi/ at main · expo/fyi · GitHub
