Fix — Add localhost to Sanity CORS

Go to sanity.io/manage

Select your brands-digitals project

Click API in the left sidebar

Scroll to CORS Origins

Click Add CORS Origin

Add exactly: http://localhost:3000

Check Allow credentials ✅

Click Save

Also add these while you're there so you don't hit this again on deployment:

http://localhost:3000 ✅ Allow credentials https://brandsdigitals.com.ng ✅ Allow credentials https://brandsdigitals.vercel.app ✅ Allow credentials

Then check your .env.local

The URL in the error shows v2026-04-01 as your API version. Make sure your env file matches:

env

NEXT_PUBLIC_SANITY_API_VERSION=2026-04-01

Whatever version is in that URL — use that exact string in your env variable.

After savi

ng CORS, restart your dev server

bash

# Stop the server (Ctrl+C) then: npm run dev

That should clear it. The request will go through once Sanity whitelists your localhost origin.
