I’m building a React + TypeScript project on Replit and running into a blocking issue. When I try to build the client for production, I get this error:

client/src/main.tsx (2:7): “default” is not exported by “client/src/App.tsx”, imported by “client/src/main.tsx”.import { Switch, Route } from “wouter”;
import { QueryClientProvider } from “@tanstack/react-query”;
import { Toaster } from “@/components/ui/toaster”;
import { TooltipProvider } from “@/components/ui/tooltip”;
import Home from “@/pages/Home”;
import Dashboard from “@/pages/Dashboard”;
import Login from “@/pages/Login”;
import NotFound from “@/pages/not-found”;

function Router() {
return (

);
}

function App() {
return (

);
}

export default App;

have you tried looking up what could cause this error?
