Client Side Rendering breaks static prerendering (?)

[jackgray]

honestly pretty confused here. Prerendering was fine before proceeding to adding the client side rendering feature. Cloned repo does not build.

in production mode building gives

`[= ] info - Generating static pages (0/4)
Error occurred prerendering page "/client-side". Read more: https://nextjs.org/docs/messages/prerender-error

Error occurred prerendering page "/404". Read more: https://nextjs.org/docs/messages/prerender-error
`
and so on.

and in development (unminified error reporting)
[= ] info - Generating static pages (0/4)Warning: React.jsx: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports. at MyApp (/Users/j/next-with-apollo/.next/server/pages/_app.js:46:3) at AppContainer (/Users/j/next-with-apollo/node_modules/next/dist/next-server/server/render.js:27:952)

Running getStaticProps in dev is a known issue, fixed by running in production mode. This does not resolve the issue with this repo.

The issue did not arise until adding client side rendering feature in the tutorial.
