Either you passed a non-internal href to a next/link component or you called Router#push or Router#replace with one.

Possible Ways to Fix It

Look for any usage of next/link or next/router that is being passed a non-internal href and replace them with either an anchor tag () or window.location.href = YOUR_HREF.
