Sentry.init()

Sentry.init({
  dsn: 'MY_DSN',

  // Adds more context data to events (IP address, cookies, user, etc.)
  // For more information, visit: https://docs.sentry.io/platforms/react-native/data-management/data-collected/
  sendDefaultPii: true,

  // uncomment the line below to enable Spotlight (https://spotlightjs.com)
  // spotlight: __DEV__,
});

Steps to Reproduce

1. npx @react-native-community/cli@latest init AwesomeProject --version 0.79.5

2. npx install-expo-modules@latest (switch to Expo bare workflow)

3. npx @sentry/wizard@latest -i reactNative (wizard added Sentry config)

   • Are you using Sentry SaaS or self-hosted Sentry? YES
   • Do you already have a Sentry account? YES
   • Do you want to enable Session Replay to help debug issues? NO
   • Do you want to enable the Feedback Widget to collect feedback from your users? NO
   • Optionally add a project-scoped MCP server configuration for the Sentry MCP? NO
   • Have you successfully sent a test event? YES

4. Android release build & run:
   ./gradlew assembleRelease (for android)
   npx expo run:android --variant release

5. iOS release build & run:
   npx expo run:ios --configuration release

Trigger a JS error

with iOS release or Android release

(e.g., throw new Error('Hello, Sentry!')).

Expected Result

Source maps with Debug IDs are uploaded automatically.

Actual Result

Sentry UI shows minified stack (app:///index.android.bundle … line 1:xxxxx), app:///main.jsbundle
“Source Map Uploads” page says No source maps uploaded.

[lucas-zimerman]

Hi and thank you for opening this issue! Before anything I have a few questions:

• Are you using Sentry SaaS or self-hosted Sentry?

Would you be able to confirm that you are using Sentry.io?

Are you making the source maps upload locally?

Do you See any Sentry CLI logs during the assembly release phase?

[sebastian7722]

Answers to your questions:
Are you using Sentry SaaS or self-hosted Sentry? I am using Sentry SaaS at sentry.io.
Would you be able to confirm that you are using Sentry.io? I confirm that i am using Sentry.io
i have configuration with defaults.url=https://sentry.io/ in sentry.properties

Are you making the source maps upload locally? Yes. I’m building and trying to upload locally on macOS (no CI).
Do I see Sentry CLI logs during assembleRelease? Yes: https://pastebin.com/5S8aT9dy
