Syntax Error: "errorMessage" is read-only

[ueatest]

React Native: v0.29.2
OS: Mac
Error occurs on iOS when react-native run-ios is run on a new project after react-native init project.
Haven't tested on Android.

Found this being fixed in #8347 (0.30-rc).

Closing this because a fix is ready and will be going on in a future release.
