I deployed my React web work as a test at Vercel but the API didn't work and my web now is Empty.. my project and api works perfectly in my localhost ! some one knows why ?
my empty web :- https://web-3-0-prokect-1.vercel.app/
api code in the useEffect hook:- https://github.com/Adelndf/web.3.0-prokect-1/blob/master/src/App.js
by the way im new in coding so some of my coding words or terms might be little bit weird :) hopefully someone understand my issue here
