custom-server-typescript: all routes return 404 on next.js 5.1.0 but work fine on 5.0.0

• I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

The custom-server-typescript example should work as expected on next.js 5.1.0. All routes should resolve to their respective pages in the pages/ folder.

Current Behavior

The custom-server-typescript example's routes all return 404 on next.js 5.1.0 but work fine on 5.0.0

Steps to Reproduce (for bugs)

1. clone the custom-server-typescript example
2. follow steps to install dependencies and run example
3. navigate to the index, a or b routes
4. all routes return 404 instead of their respective pages
5. downgrade next.js to 5.0.0 (eg. npm install next@5.0.0 --save)
6. rerun the example (eg. npm run dev)
7. navigate to the index, a and b routes and they work as expected

Your Environment

Tech	Version
next	v5.1.0
node	v9.9.0 x64
OS	Windows 10 x64
browser	Chrome 65.0.3325.181

Having the same problem here but with the with-typescript example built with create-next-app. Played around a bit with file extensions, and my pages render correctly if they are .js, but aren't rendered at all if they are .tsx or .ts.

Upgrade @zeit/next-typescript to the latest version as suggested in the blogpost.

yarn add @zeit/next-typescript@latest
