This document https://nextjs.org/docs/app/api-reference/functions/next-request#geo says that req.geo will be provided on vercel deployments, and mine is not providing it on my vercel deployment. I am attempting to access this up from the GET(req: NextRequest) handler.

export const dynamic = "force-dynamic"; // defaults to auto

export async function GET(req: NextRequest) {
  // all undefined
  // provided by vercel
  const city = req.geo?.city;
  const country = req.geo?.country;
  const region = req.geo?.region;

I am on next 14.2.3
