Duplicate Polyfills from Polyfill.io

Why This Error Occurred

You are using Polyfill.io and including duplicate polyfills already shipped with Next.js. This increases page weight unnecessarily which can affect loading performance.

Possible Ways to Fix It

Remove all duplicate polyfills that are included with Polyfill.io. If you need to add polyfills but are not sure if Next.js already includes it, take a look at the list of supported browsers and features first.
