adapter-node is erroring on all requests

Updating adapt-node from "1.0.0-next.09", to "1.0.0-next.11" is now resulting in the error always being raised when running the server.

node build/index.js

Listening on port 3000
node:internal/process/promises:245
          triggerUncaughtException(err, true /* fromPromise */);
          ^

  input: '/',
  code: 'ERR_INVALID_URL'
}

^ This results in the server crashing and not serving a 404 which is also interesting

I have confirmed that downgrading back to 09 fixes the issue on my end.

This snuck through CI because the adapters don’t currently have tests - #639.

I’ll open a PR with a fix for the Node adapter and the simplification for the Vercel adapter.

My proposed fix is

but I don’t know why tests didn’t catch this.
