IIS "Cors" configuration problem for Node.js backend

I have a node.js backend, and in my server.js file I have this:

const app = express();
app.use((req, res, next) => {
res.setHeader("Access-Control-Allow-Origin", "*");
res.setHeader(
"Access-Control-Allow-Methods",
"OPTIONS, GET, POST, PUT, PATCH, DELETE"
);
res.setHeader("Access-Control-Allow-Headers", "Content-Type, Authorization");
next();
});


It is working correctly in the Localhost, but after uploading to the server, it gives this Cors error...
