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
