Uncaught errors are not captured on React Native #655
Description
When using Raven in ReactNative, any error that is thrown outside of a try-catch block is not captured. It looks like there was an attempt to capture by calling ErrorUtils.setGlobalHandler. Unfortunately, in production the errors are never captured because the app crashes before the request is complete.
One option is to skip the defaultHandler, which is what causes the app to crash. However, the best behaviour is application-specific.
Perhaps the best solution is to avoid attempting calling ErrorUtils.setGlobalHandler at all in the React Native plugin, and instead to provide documentation for users to do it themselves?

I have the same problem, in production no errors are logged.
I don't understand your workaround to get this working.

@Kerumen . Sorry. My description was a suggestion for how to fix the library, rather than a workaround for users, which is why it was confusing.
To understand how to change the behaviour yourself, I'd recommend reading through this library's React Native plugin: https://github.com/getsentry/raven-js/blob/master/plugins/react-native.js#L59 . You'll see where it calls
ErrorUtils.setGlobalHandlerand passes the error along toRaven.captureException. You can override this in your own code, and avoid callingdefaultHandler.apply. Then the error will be reported, but the app won't crash.To restart the app when there is an error, I used
CodePushwhich already has a utilityCodePush.reloadApp. If you aren't usingCodePushyou'll likely be able to reimplement that functionality, or find a library to do it for you.Kerumen commentedon Jul 26, 2016
Thanks. I still have some troubles with CodePush and Sentry.
Can you help me? I reached you on Twitter :) Thanks!

This will likely be addressed by #626

Hey,
Check out our official client for react-native -> https://github.com/getsentry/react-native-sentry
Closing this here since it's obsolete.
If you're still having troubles, please create an issue there.
Thanks
