getSentryExpoConfig(5.26.0) no longer unobfuscates stack traces with source maps

[navignaw]

OS:

• Windows
• MacOS
• Linux

Platform:

• iOS
• Android

SDK:

• @sentry/react-native (>= 1.0.0)
• react-native-sentry (<= 0.43.2)

SDK version: 5.26.0

react-native version: 0.73.8

Are you using Expo?

• Yes
• No

Are you using sentry.io or on-premise?

• sentry.io (SaaS)
• on-premise

Configuration:

Same as recommended in the guide: https://docs.sentry.io/platforms/react-native/sourcemaps/uploading/expo/

---

I have the following issue:

When building an Expo app with EAS build and the getSentryExpoConfig function with the annotateReactComponents set to true, stack traces no longer appear to be unobfuscated. EDIT: I'm also seeing no stack traces at all when this is set to false.

I suspect that this is due to the code conditionally running either withSentryFramesCollapsed or withSentryBabelTransformer, but the latter function is missing some logic for the source maps.

Steps to reproduce:

• Follow the guide to configure an expo project: https://docs.sentry.io/platforms/react-native/sourcemaps/uploading/expo/
• Update the getSentryExpoConfig to include annotateReactComponents: true, like in the docs for Session Replay
• Trigger an error

Actual result:

The stack trace is still obfuscated:

Expected result:

The stack trace is unminified

[navignaw]

Sorry, I'm no longer actually sure if annotateReactComponents is the cause, or if this was just a regression in 5.26.0. Even after setting it to false, I was still unable to see unminified stack traces / source maps.

@navignaw thanks for the report and the follow-up. Would you be able to try and reproduce this with a previous version of @sentry/react-native?

Hi @navignaw,
thank you for the message,

could you share a code snippet of how are you testing this?

For example, are you using Sentry.captureException(new Error('My error'))?

Does it happen in debug or release builds? (I expect release as you mention when building in EAS)

Can you check your EAS build logs for the source maps upload? When you search for sentry in the logs, you should be able to see what files were uploaded to Sentry. On Sentry side when you open your project settings you should see the source maps uploaded.
