Sentry.init()

import * as Sentry from '@sentry/react-native';

export const navigationIntegration = Sentry.reactNavigationIntegration();

Sentry.init({
dsn: 'https://[email protected]/4510514102337536',
tracesSampleRate: 1.0,
replaysSessionSampleRate: 0,
replaysOnErrorSampleRate: 1,
integrations: [
navigationIntegration,
Sentry.reactNativeTracingIntegration({ idleTimeoutMs: 1000 }),
Sentry.mobileReplayIntegration(),
],
debug: DEV,
});

Steps to Reproduce

I created a simple react native application for mobile that demonstrates going through different pages and calling an error on the second page. Link for repro: https://github.com/colinkawai/SampleRateRN

Expected Result

I expect that traces to be attached to a replay when errorSessionSampleRate is 1. Currently in the replays section you'll see a replay with everything but the traces. The traces are sent still. I see it in the traces section. I expect either the replay id in the buffer to be attached to the current trace or vice versa where the trace id is attached to the replays.

Actual Result

There's no traces connected to replays in the replays view.
