No Server Import In Page

Prevent usage of next/server outside of middleware.js.

Why This Error Occurred

next/server was imported outside of middleware.{js,ts}.

Possible Ways to Fix It

Only import and use next/server in a file located within the project root directory: middleware.{js,ts}.

// middleware.ts

import type { NextFetchEvent, NextRequest } from 'next/server'

export function middleware(req: NextRequest, ev: NextFetchEvent) {
  return new Response('Hello, world!')
