Describe the Bug

With custom rewrites in next.config.js, the application breaks when hitting /api/ routes in Production mode.

Expected Behavior

The application should not break on /api routes.
A break that occurs in production mode should have occurred in development mode.

To Reproduce

1. Add a custom rewrite to next.config.js:

const rewrites = async () => [
  {
    source: "/:path*",
    has: [
      {
        type: "host",
        value: "(?<host>.*)",
      },
    ],
    destination: "/:path*?host=:host",
  },
];

(rewrites is then used in config...)

2. During development mode, running is fine.
3. Build the application.
4. Start the application and hit any route except home.

An error as follows is experienced:

TypeError: Cannot read property '__nextLocale' of undefined
at Router.execute (C:....\node_modules\next\dist\next-server\server\router.js:19:712)
at processTicksAndRejections (internal/process/task_queues.js:93:5)

at async Server.handleRequest (C:....\node_modules\next\dist\next-server\server\next-server.js:34:504)

Hey @simmbiote, I opened an issue with a similar behaviour but when on purpose open the page with 2 slashes ("//"), to see if it would go to error page.

Hi, I'm gonna close this as this appears to be working correctly in the latest version of Next.js v11.1.2 please update and give it a try!
