How to: solve 429 fetch errors on NextJS and Vercel

Learn to solve an unexpected application error on client-side

Recently, I added Medium Feed integration into my personal website. I chose api.rss2json.com to help fetch the feed and convert it to JSON format. Everything was doing well on local testing. However, it returned 429 errors when deployed to Vercel.

Application error: a client-side exception has occurred (see the browser console for more information).

Sample of fetch is provided below:

Before vs. After

Final Output:

My personal website: https://1998.media

Hope help :)
