`NextResponse.next()` used in a Route Handler in the App Router

Why This Error Occurred

Route Handlers in the Next.js App Router do not support using the NextResponse.next() method to forward to the next Proxy.

The Route Handler is considered the end of the proxy "chain". Handlers must always return a Response object instead.

Possible Ways to Fix It

Remove the NextResponse.next() and replace it with a correct response handler.
