Sentry.init()

const navigationIntegration = Sentry.reactNavigationIntegration({
	enableTimeToInitialDisplay: true,
});
Sentry.init({
	release: SENTRY_RELEASE,
	dist: SENTRY_DIST,
	dsn: "https://###@###.ingest.us.sentry.io/###",
	environment: __DEV__ ? 'development' : 'production',
	// Set tracesSampleRate to 1.0 to capture 100% of transactions for performance monitoring.

Steps to Reproduce

1. Run the app in iOS
2. Crash the app using Sentry.captureException(new Error('test error'))
3. The app crashes but no record in the dashboard.

Expected Result

Crash report is added in the dashboard

Actual Result

No crash recorded

Here is the logs when I invoke Sentry.captureException(new Error('test error'))

LOG  Sentry Logger [log]: [TouchEvents] Touch event within element: Text
LOG  Sentry Logger [log]: [UserInteraction] User Interaction Tracing can not create transaction with undefined elementId.
DEBUG  Sentry Logger [debug]: [Sentry] MobileReplay not sampled for event 9f3b36b9cef140dfa829163e7fd0a06a.

Hi @uypao,
thank you for the details.

The application should not crash after calling Sentry.captureException(new Error('test error')). This code should only report the test error to Sentry. But the application should keep running.

To debug this further could you share with us logs from the crash? Or minimal reproducible example?

Does a React Native Red Box appears before the crash? Or if you are using Xcode, could you share with us stack trace of the crash?

[uypao]

@krystofwoldrich Sorry I was using different types of error to log which would work. I was using Sentry.nativeCrash() to test the crash the app. Both Sentry.captureException(new Error('test error')) and Sentry.nativeCrash() did not log anything in the dashboard.

Here are the logs:

LOG Sentry Logger [log]: [TouchEvents] Touch event within element: Text LOG Sentry Logger [log]: [UserInteraction] User Interaction Tracing can not create transaction with undefined elementId. DEBUG Sentry Logger [debug]: [Sentry] MobileReplay assign already recording replay a96e1cdce17b4a2f8c442d21dedc92d6 for event 8e72db7e47964c098940eb754c334c1b.

[uypao]

The react native red box does not appear before the crash

[krystofwoldrich]

For Sentry.nativeCrash() please test this functionality in Release build of the application, note that the crash is sent on the next application start.

---

For Sentry.captureException(new Error('test error')) the issue should appear in Sentry within few seconds.

If no events are no being received check that you simulator/phone is able to access the DSN. You can for example try to open the DSN in your simulator's/phone's browser, the server should respond with 404.

[uypao]

DSN is accessible on my device.

Not sure what else to look for. It stopped working after upgrading from 5.5.0 to 6.5.0

[krystofwoldrich]

Thank you for confirmation,
since the issue is on iOS can you share with us the Simulator/Device console (from app start till calling captureException in JS), so we can investigate if the issue possibly in the native code?
