--- title: No Server Import In Page --- > Prevent usage of `next/server` outside of `proxy.js`. ## Why This Error Occurred `next/server` was imported outside of `proxy.{js,ts}`. ## Possible Ways to Fix It Only import and use `next/server` in a file located within the project root directory: `proxy.{js,ts}`. ```ts filename="proxy.ts" import type { NextFetchEvent, NextRequest } from 'next/server' export function proxy(req: NextRequest, ev: NextFetchEvent) { return new Response('Hello, world!') } ``` ## Useful Links - [Proxy](/docs/pages/api-reference/file-conventions/proxy)
