logging out params gave undefined

it was tested with this link http://localhost:3000/api/auth/server-auth?code=somecode&guild_id=12345&permissions=8

Not path params.

joulev
import { type NextRequest } from 'next/server'

export function GET(request: NextRequest) {
  const searchParams = request.nextUrl.searchParams
  const name = searchParams.get('name')
  return new Response(name ? `Hello ${name}!` : '`name` is not provided.')
}
American ChinchillaOP
import { notFound } from "next/navigation"
import { NextResponse, type NextRequest } from "next/server"

export function GET(req: NextRequest) {
  const guild_id = req.nextUrl.searchParams.get("guild_id")
  if (!guild_id) {
    notFound()
  }
  return NextResponse.redirect(`/dashboard/${guild_id}`)
}

I think if you use redirect() there you don’t need absolute url
