React Native app not building for Android - SyntaxError: \ u may be followed by a Unicode character sequence

Question

My application works fine on iOS, but will not work on Android. Last week I spent a lot of time for it to work, and thought it was so, and the problem returned.

Magazines show

SyntaxError: \u can only be followed by a Unicode character sequence 

When I reboot, I get a white screen, no errors are displayed, and I can not get past this, and it does not change whether I connect to the debugger or not.

I looked at the source and the error comes from the next line

What is it from React source https://github.com/facebook/react-native/blob/a974c140db605ecbdf8d3faa7a079b7e2dcebb09/Libraries/ReactNative/YellowBox.js#L263

After the update, I get the following error in logcat, although there is nothing in the emulator.
