react-error-overlay: uncaught typeerror on using right/left arrow

[Gandem]

Hello !

First of all thanks a lot for the upgrade and the hard work, create-react-app is completely awesome 😄 !

This issue was discovered when updating to react-scripts@1.0.0

Description

On launching an empty app created with create-react-app, and using right/left arrow on the keyboard (when no overlay error is present) it logs an error in the console:

Uncaught TypeError: Cannot read property 'error' of undefined
    at renderErrorByIndex (overlay.js:66)
    at switchError (overlay.js:86)
    at shortcutHandler (overlay.js:145)
    at keyHandler (shortcuts.js:17)

Reproducible Demo

I could reproduce this error on a new react project created with create-react-app, as well as old projects I upgraded.

For info, I'm on Mac OSX Sierra on Chrome 57.

I would be glad to send a Pull Request and work on this issue, if someone could give me some hints to what's actually happening on here !

react-scripts@1.0.1 should be out with a fix.
Can you please verify it helps?

Just upgraded to react-scripts@1.0.1 on some of my projects, and it worked perfectly. Thanks a lot 🙌 !

The fix doesn't seem to be working in react-scripts@1.0.3. I can see it's there, but when I look at the react-error-overlay package in my node_modules folder it has the correct version number (1.0.3), however, the fix is not present in the overlay.js file.

Oops, my fault. Will publish 1.0.4 soon.

Should be fixed in 1.0.4 (just published).
