React-native errors all show 'native code' transaction

SDKs
5

I’m seeing something that might be related.

My react-native app is reporting errors via raven. Everyone is working fine on ios, but not on android. On android everything looks great in development, but in release it always reports the stack as just [native code]. Just one frame.

Besides minification and bundling, the only difference I can see between the two is this small change from adb logcat.

Dev:

12-19 17:35:38.375 31961  2904 W ReactNativeJS: My error message string here
12-19 17:35:38.385 31961  2904 W ReactNativeJS: { [My error message string here]
12-19 17:35:38.385 31961  2904 W ReactNativeJS:   line: 106404,
12-19 17:35:38.385 31961  2904 W ReactNativeJS:   column: 29,
12-19 17:35:38.385 31961  2904 W ReactNativeJS:   sourceURL: 'http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false&minify=false' }

Release:

12-19 17:29:21.585 30613 30647 W ReactNativeJS: My error message string here
12-19 17:29:21.605 30613 30647 W ReactNativeJS: { [My error message string here] line: 797, column: 2554, sourceURL: 'index.android.bundle' }

I can’t really imagine that the number of linebreaks there is relevant, so please let me know if I can help provide more info in any way.
