The page component at "node_modules\gatsby-plugin-offline\app-shell.js" didn't pass validation

The page component must export a React component for it to be valid

Steps to reproduce

1. clone repo gatsbyjs.org source

2. npm install / npm update

3. gatsby build

Downgrading gatsby to 1.9.186 should allow you to build gatsby. Will investigate how to properly fix that
