I wrote this code : "import { clerkMiddleware, createRouteMatcher } from "@clerk/nextjs/server"; const isProtectedRoute = createRouteMatcher(["/dashboard(.*)"]); export default clerkMiddleware((auth , req) => { if (isProtectedRoute(req)) { auth().protect() }; }); export const config = { matcher: [ // Skip Next.js internals and all static files, unless found in search params '/((?!_next|[^?]*\\.(?:html?|css|js(?!on)|jpe?g|webp|png|gif|svg|ttf|woff2?|ico|csv|docx?|xlsx?|zip|webmanifest)).*)', // Always run for API routes '/(api|trpc)(.*)', ], };". But when I open the localhost it is showing as shown in the image though I have given my secret key
