description	Capture HTTPS requests from Next.js server-side fetch() and Server Components with the Proxyman pre-configured Terminal from Automatic Setup.

NextJS (fetch)

1. Problem

• Proxyman can't capture any traffic from use server code in NextJS
• It's because fetch in NextJS doesn't respect the system HTTP proxy. Therefore, no traffic goes through the Proxyman app.

2. Solution

1. Start the pre-configured Terminal: Setup menu -> Automatic Setup -> Click "Open New Terminal"
2. A new Terminal opens -> Start your NextJS server in this Terminal. For example: npm run dev
3. Use no-cache on fetch

export default async function MyPage() {
  const res = await fetch('https://httpbin.org/anything', { cache: 'no-cache' }) // no cache, or no request is sent to Proxyman
  return <div>My Page{res.text()}</div>
}

4. Reload your website
5. Done ✅ The Proxyman app captures your HTTP traffic
