Reflect is not defined

[Valodya]

After adding the plugin I have the error in terminal

 ReferenceError: Reflect is not defined
....

I'm using this plugin for correct extending Error class, and when I try to throw an error I have error "Reflect is not defined"

After a quick investigation I've noticed that you are using Reflect

any ideas how to fix it?

Currently the expectation is that you'd be loading babel-polyfill or using babel-plugin-transform-runtime. It's possible that the usage of Reflect may change in the future but hard to say.
