Expo Production Mode

Hello! 👋

Issue Description

I have a React Native application with Expo and I’m trying to throw an error that is triggered by a button.

onPress={() => { throw new Error('This is a test error!'); }}

I’m running the application in Production Mode using expo start --ios --no-dev --minify to see the error screen and try to simulate a real case, but I’m not able to see it. In development mode, I have no problems following the example demo on Expo: https://snack.expo.io/@carloscuesta/react-native-error-boundary.

Would anyone happen to know how I could go about fixing this issue?

Thanks for the help and time!

Hey @LucasOliveiraS can you try running the same code from the Expo example in production mode to check if you can see the error screen?

I think the problem is that you’re throwing inside of an event handler and as stated in the React docs, error boundaries don’t catch this

Hey! 👋🏼

I’ve been not using Expo for a while, but I found this on the docs:

Not sure if this will be of any help but my guess is that Expo is handling the error in Production mode reloading the application and you’re not able to see the error screen 😊
