…date comments The blocklist regex `.*\\android\\.*` was too broad - after being combined by Metro's exclusionList, it blocked `expo-symbols/build/android` directory from being resolved, causing Android bundle export to fail. Scope the regex to only block the sample app's own android/ build directory. Also update comments to reflect SDK 55 and RN 0.83. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

    "name": "sentry-react-native-expo-sample",
    "slug": "sentry-react-native-expo-sample",
    "jsEngine": "hermes",
-    "newArchEnabled": true,


In React Native 0.83 (Expo SDK 55), the New Architecture is the default. The newArchEnabled flag is no longer a valid configuration key — expo-doctor flags it as an error. Since it's now on by default, explicitly setting it is both unnecessary and invalid.

    ...getBlockList(monorepoPackages, ['react-native', 'react']),
-    new RegExp('.*\\android\\.*'), // Required for Windows in order to run the Sample.
+    new RegExp(`${projectRoot.replace(/[.*+?^${}()|[\]\\]/g, '\\$&')}[/\\\\]android[/\\\\].*`), // Required for Windows in order to run the Sample.


The old regex was too broad and broke module resolution
