Configuration:

(@sentry/react-native)

Sentry.init({
  dsn:
    '###',
  environment: process.env.NODE_ENV,
  enableAutoSessionTracking: true,
  release: `${DeviceInfo.getBundleId()}-${DeviceInfo.getVersion()}`, // com.helloapp-0.0.2
  dist: DeviceInfo.getBuildNumber(), // 4
  debug: true,
});

---

I have following issue:
Source code was not found error on the dashboard even after source map is available

Steps to reproduce:

• Step 1: React native init & setup @sentry/react-native
• Step 2: Configured Sentry

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

Sentry.init({
  dsn:
    '###',
  environment: process.env.NODE_ENV,
  enableAutoSessionTracking: true,
  release: `${DeviceInfo.getBundleId()}-${DeviceInfo.getVersion()}`,
  dist: DeviceInfo.getBuildNumber(),
  debug: true,
});

• Step 3: Build React Native app yarn run android
• Step 4: Start the app yarn run start
• Step 5: Create a bundle folder mkdir bundle
• Step 6: Bundle the app

react-native bundle \
    --platform android \
    --dev false \
    --entry-file index.js \
    --assets-dest bundle \
    --bundle-output bundle/index.android.bundle \
    --sourcemap-output  bundle/index.android.bundle.map

• Step 7: Upload source map

node_modules/@sentry/cli/bin/sentry-cli  releases --org fivoto --project react-native  files com.helloapp-0.0.2 upload-sourcemaps --dist 4 --strip-prefix . --rewrite ./bundle

• Step 8: Trigger an error

...
  const _sendErrro = () => {
    try {
      var e = helo;
      throw e;
    } catch (error) {
      Sentry.captureException(error);
    }
  };

....
  <Button onPress={_sendErrro}> Throw Error</Button>
...

Actual result:

On first glance, the stack trace already looks unminified and doesn't need a sourcemap. This looks like an error from a development build which should already be unminified. In the error above, it says it's looking for an index.js bundle while the bundles you've uploaded are index.android.bundle which is why it's saying sourcemap not found.

Can you paste the event's JSON for me so I can give a closer look, and also try it in a release build?

[seyedasfar]

That's was in the development environment and I build my application and try the same way again and still, the same Source code was not found with two different messages.

Hmm this one is actually a separate issue and should be fixed by this: getsentry/sentry-java#1064. You don't need to worry about FileObserver.java and Thread.java, they're how our Android SDK read the events from React Native and shouldn't even be logged.

As the original issue should be resolved, let's close this for now.
