I have a simple server. Code is explained below:

const express = require("express");
 
const app = express();
 
app.set("view engine", "hbs");
 
app.get("/about-me", function(_, response) {
    response.render("about_me.hbs");
});
app.get("/", function (_, response) {
    response.render("index.hbs");
});
app.all(/.*/, function (_, response) { // 404 page
    response.sendStatus(404); // set status code to 404
    response.send("<h1>404 Not Found</h1>"); // send a body
}
app.listen(3000);

But when I opened http://localhost:3000/not-exist , there was "Not Foun<" text. Why it's happening?
