I don't understand why is not working. The compiler is asking for the async in the await function in router, and I have the async in router exports.

The problem in IMG

Server:

const http = require("http");
const router = require("./router");

module.exports = http.createServer((request, response) => {
    console.log(request.url);
  
    try {
        const content = await router(request, response);
        return response.end(content);
    } catch (error) {
        
        response.writeHead(404,{
            'Content-Type': 'text/html',
        });
        response.end(`<h1>${error.message}</h1>`);
    }
});

Router:

const { parse } = require("url");
const indexAction = require("./actions/index");

const routes = {
  "/": indexAction,
};

module.exports = async (request, response) => {
  const parseUrl = parse(request.url, true);
  const route = parseUrl.pathname;

  if (routes[route]) {
    return await routes[route](request, response, parseUrl.query);
  }

  throw new Error("404 Not Found");
};

Please post your code in text form and not image form, as this makes it easier for others to troubleshoot your code. – aplua Jul 09 '22 at 11:21
please post the code and error, not the image – Rinkesh P Jul 09 '22 at 11:21
Do you mean like this? – Filipe Silva Jul 09 '22 at 11:28

you need to make the callback async `module.exports = http.createServer(async (request, response) => {` – MWO Jul 09 '22 at 11:30
either what @MWO suggests or use promise chaining. – Rinkesh P Jul 09 '22 at 11:31
Yes, thank you. Just to be clear. So when I use await inside a lambda function, I need also to use it in the parameters of the lambda function? – Filipe Silva Jul 09 '22 at 11:36
Change this line `module.exports = http.createServer((request, response) => {` to this `module.exports = http.createServer(async (request, response) => {` – Youssouf Oumar Jul 09 '22 at 11:38
