I just switched to App Routing and use NextResponse.
Even though the doc explains it like the following it wont let me

return NextResponse.json({ token }, { status: 200 })


second param can only be a response init. I dont know how to set the response code withing a NextResponse. For a normal response it works

You shouldnt need to use NextResponse.json anymore, the Response.json should work fine

That looks right for the app router, can you give more context? is it in a route.ts/js and a GET/POST etc?

The route.ts looks like this currently in the path src/app/api/login/route.ts

import {NextRequest, NextResponse} from 'next/server'
import {authenticateUser, generateToken} from '@/services/authService'

// Handle POST request
export async function POST(req: NextRequest) {
    try {
        const { username, password } = await req.json()
        const user = await authenticateUser(username, password)
        const token = generateToken(user.id)
        return NextResponse.json({ token })  // Status code 200
    } catch (error) {
        if (!(error instanceof Error)) {
            return NextResponse.json({ error: "Unknown Server error" })
        }

        return NextResponse.json({ error: error.message })  // Status code 401
    }
}

// Handle GET request (if needed)
export async function GET(req: NextRequest) {
    throw new Error('Invalid credentials')
    // Implement logic for GET requests, if necessary
    return NextResponse.json({ message: "GET method not implemented" })
}
i can also confirm that i can reach the POST endpoint so the routing seems to work (not the GET endpoint tho but thats another topic)
this is when i try to add a status

Ok little update: So apparently it works codewise. The response code seems to change. Just the Webstorm/Typescript cannot handle this?
