Callback on function not working

I am working on a Node.js web function to retrieve data from an API and add it to my Appwrite database. However, when I tried debugging if the data is being retrieved, the callbacks from the http function do not seem to work as I get an empty response when I try to execute the function

TypeScript

import { Client, Databases } from "node-appwrite";
import http from 'http';

export default async ({ req, res, log, error }) => {
    const client = new Client();
    const databases = new Databases(client);

    client
        .setEndpoint(process.env.APPWRITE_BACKEND_ENDPOINT)
        .setProject(process.env.APPWRITE_PROJECT_ID)

    if(req.method == "POST") {
        let data = {};
        const options = {
            hostname: 'http://api.syntesio.ro',
            port: 80,
            path: '/SyntesioServices/api/v1/core/product/list',
            method: 'GET',
            headers: {
                'Authorization': process.env.CHARA_API_AUTH_KEY
            }
        }
        const request = http.request(options, (response) => {
            response.setEncoding('utf-8');

            response.on('data', (chunk) => {
                return res.json(JSON.parse(chunk));
            });

            response.on('end', () => log(`Response data string end`));
        })

        request.on('error', (error) => error(error.message));
        request.end();

        return res.json(data);
    }
};

TL;DR

Developers faced an issue with callbacks not working in their Node.js function while trying to retrieve data and encountered an empty response. They sought to use async/await with `http.request` function but struggled to find a solution. To resolve the problem, they need to wait for the response before proceeding with the logic instead of returning an empty response immediately.
