On Expo SDK 54 (React Native 0.81), using @sentry/react-native ~7.1.x can lead to Metro bundling failures (TypeError: countLines is not a function).
Sentry fixed this upstream in version 7.2.0 (they vendored the countLines logic to avoid Metro internals).
Current Behavior
  • Expo Doctor currently expects @sentry/react-native ~7.1.0.
  • After upgrading to 7.2.x (which resolves the bundling error), expo-doctor reports:
✖ Check that packages match versions required by installed Expo SDK
Minor version mismatches
@sentry/react-native expected ~7.1.0 found 7.2.0
Workaround
Adding to package.json:
{
"expo": {
"install": {
"exclude": ["@sentry/react-native"]
}
}
}
This suppresses the warning and allows healthy builds with Sentry 7.2.x.
Request
Please update Expo’s dependency mapping so that @sentry/react-native ~7.2.x is accepted by default (or broaden the accepted range). This prevents developers from hitting the Metro error with ~7.1.x and avoids having to manually exclude the package.
