Some of the conditions are omitted in middleware

some of conditions are not checked by the middleware as when a user is authenticated and navigates to /register he should be redirected back to /home but it does not do that only /login condition works but others do not work using codes below

import { verify } from 'jsonwebtoken';
import { NextResponse } from 'next/server'
import type { NextRequest } from 'next/server'
import { COOKIE_NAME } from './app/constants/cookie';
import { cookies } from 'next/headers';

export async function middleware(req: NextRequest) {

  const res = NextResponse.next()

  const token = req.cookies.get(COOKIE_NAME);
 

    if (!token) {
        if (req.nextUrl.pathname.startsWith('/home')) {
            const redirectUrl = req.nextUrl.clone()
            redirectUrl.pathname = '/login'
            redirectUrl.searchParams.set(`redirectedFrom`, req.nextUrl.pathname)
      return NextResponse.redirect(redirectUrl)
          }
else{
            const redirectUrl = req.nextUrl.clone()
        redirectUrl.pathname = '/'
        redirectUrl.searchParams.set(`redirectedFrom`, req.nextUrl.pathname)
  return NextResponse.redirect(redirectUrl)
          }
     }

     const user = JSON.parse(token.value)

  if (user.role === "USER") {
     if (req.nextUrl.pathname.startsWith('/adupload')) {
        return NextResponse.rewrite(new URL('/home', req.url))
      }

      if (req.nextUrl.pathname.startsWith('/login')) {
        const redirectUrl = req.nextUrl.clone()
        redirectUrl.pathname = '/home'
        redirectUrl.searchParams.set(`redirectedFrom`, req.nextUrl.pathname)
  return NextResponse.redirect(redirectUrl)
      }

      if (req.nextUrl.pathname.startsWith('/register')) {
        const redirectUrl = req.nextUrl.clone()
        redirectUrl.pathname = '/home'
        redirectUrl.searchParams.set(`redirectedFrom`, req.nextUrl.pathname)
  return NextResponse.redirect(redirectUrl)
      }
  }
  return res
}

export const config = {
  matcher: [
    '/home/:path*',
   
  ],
}

import { verify } from 'jsonwebtoken';
import { NextResponse } from 'next/server'

  const token = req.cookies.get(COOKIE_NAME);
 

    if (!token) {
        if (req.nextUrl.pathname.startsWith('/home')) {
            const redirectUrl = req.nextUrl.clone()
            redirectUrl.pathname = '/login'
            redirectUrl.searchParams.set(`redirectedFrom`, req.nextUrl.pathname)
      return NextResponse.redirect(redirectUrl)
          }
else{
            const redirectUrl = req.nextUrl.clone()
        redirectUrl.pathname = '/'
        redirectUrl.searchParams.set(`redirectedFrom`, req.nextUrl.pathname)
  return NextResponse.redirect(redirectUrl)
          }
     }

     const user = JSON.parse(token.value)

  if (user.role === "USER") {
     if (req.nextUrl.pathname.startsWith('/adupload')) {
        return NextResponse.rewrite(new URL('/home', req.url))
      }

      if (req.nextUrl.pathname.startsWith('/login')) {
        const redirectUrl = req.nextUrl.clone()
        redirectUrl.pathname = '/home'
        redirectUrl.searchParams.set(`redirectedFrom`, req.nextUrl.pathname)
  return NextResponse.redirect(redirectUrl)
      }

      if (req.nextUrl.pathname.startsWith('/register')) {
        const redirectUrl = req.nextUrl.clone()
        redirectUrl.pathname = '/home'
        redirectUrl.searchParams.set(`redirectedFrom`, req.nextUrl.pathname)
  return NextResponse.redirect(redirectUrl)
      }
  }
  return res
}

export const config = {
  matcher: [
    '/home/:path*',

It can't get to /register because of your matcher

export const config = {
  matcher: [
    '/home/:path*',
   
  ],
}

export const config = {
  matcher: [
    '/home/:path*',
   
  ],
}

this means the middleware will only activate on routes that start with /home, e.g. - /home/register - /home - /home/user/idk-whatever/123 but not on /register
