nodejs core https POST example - not working code!

node-https-post-example.js

// NOTE: This isn't working code, I rehashed it as an example from one of my projects

import https from "https";

const requestOptions = 
{
  // See https://nodejs.org/api/http.html#http_http_request_options_callback
};

const req = https.request(requestOptions, (res) => 
{
    let data = "";

    // Configure the handler to fire when response data chunks are received
    res.on("data", (d) => 
    {
        data += d;
    });

    // Configure the handler to execute when the request is complete
    res.on("end", () => 
    {    
        const ret = 
        {
            statusCode: res.statusCode,
            body: data
        };

        return callback(null, ret);
    });
});

// Configure the error handler
req.on("error", (e) => 
{
    return callback(e, {});
});

// Add the POST data
// NOTE: POSTJSON would be a chunk of JSON data - not shown here
const POSTJSONString = JSON.stringify(POSTJSON);
const HTTPBody = Buffer.from(POSTJSONString, "utf8");
req.write(HTTPBody);

// Make the request
req.end();

This almost worked. As I'm posting JSON I had to set the Content-Type in the options object to the right value. In this case...

"headers": {
  "Content-Type": "application/json",
}

Thanks for your help.
