When I deploy to vercel I get an error "ReferenceError: window is not defined".

It works fine on the my local machine.

This seems to be because of some changes to Vercel's env vars, where they no longer populate a URL one. You can update get-full-redirect-url.ts to use the following as a fix, just confirmed it works for me:

export default function getFullRedirectUrl(redirectPath: string) {
  if (redirectPath.startsWith("http")) return redirectPath;
  const baseUrl =
    process.env.URL || process.env.VERCEL_URL || window.location.origin;
  return [baseUrl, redirectPath?.replace(/^\//, "")].filter(Boolean).join("/");
}

I'll get a PR going for the template.

This has bee resolved in the legacy repo - I'll be working on a simpler starter kit for Next shortly
