Node.js higher-order function - node.js

Question

I am trying to send a http request when an event is entering, but the console outputs in the higher-order function are not working.
exports.handler = async (event) => {
const req = https.get('https://test.com', (res) => {
console.log('statusCode:', res);
console.log('headers:', res.headers);
let data = "";
res.on('data', (d) => {
data += d;
});
res.on('end', () => {
let url = JSON.parse(data);
console.log(url);
});
}).on('error', (e) => {
console.error(e);
});
return 0;
};
Happy for every help i can get!

I updated the code snippet you provided,
const https = require('https');
const func = async () => {
const req = https.get('https://test.com', (res) => {
console.log('statusCode:', res.statusCode);
console.log('headers:', res.headers);
let data = "";
res.on('data', (d) => {
data += d;
});
res.on('end', () => {
console.log({data})
let url = JSON.parse(data);
console.log(url);
});
}).on('error', (e) => {
console.error(e);
});
return 0;
};
func();
console.log('statusCode:', res.statusCode);
is the correct way to retrieve statusCode from res.
let url = JSON.parse(data);
data is not json, it cannot be parsed
res is an instanceOf IncomingMessage

Have a look at the documentation to understand what is passed on the events emitted
Run the updated code so that you can see what is logged to stdOut
