Expected Behavior

The App does not crash on launch and the JS is bundled.

Actual Behavior

The App does crash on launch and the JS is bundled.

Reproducible Demo

React Native 0.48.0-rc.1 does not throw such error and works as expected.
I am assuming that something in here v0.48.0-rc.1...v0.48.0 is causing the issue.
