节点承诺似乎在欺骗数据，有些看起来像缓冲区

我正在进行一个异步https请求。我正在取回数据，但它似乎是慢慢传入的，而不是作为服务器的单个响应返回。其中一些甚至看起来像是作为某种缓冲回来了。有人见过这样的东西吗？

我正在努力理解异步"on data"是否会支离破碎。服务器设置为返回单个响应。

//Start JS File

var port = process.env.PORT || 3000,
http = require('http'),
fs = require('fs'),
https = require('https'),
html = fs.readFileSync('index.html');
const server = http.createServer();
server.on('request', async (req, res) => {
let myPromise = new Promise((resolve, reject) => {
const data = JSON.stringify({
someData:'someData'
});
const options = {
hostname: 'gs.aURL.com',
port: 443,
path: '/openrtb2/auction',
method: 'POST',
headers: {
'Content-Type': 'text/plain',
'Content-Length': data.length,

}
};
const adRequest = https.request(options, (adResponse) => {
//console.log(`statusCode: ${res.statusCode}`);
adResponse.on('data', (d) => {
console.log(typeof d);
res.write(d);
resolve(d);
});
});
adRequest.on('error', (error) => {
reject(error);
});
adRequest.write(data);
adRequest.end();
})
.then((result) => {
console.log(result);
res.write(result);
req.end();
})
.catch((error) => {
//res.write(error);
//req.end();
});
});
// Listen on port 3000, IP defaults to 127.0.0.1
server.listen(port);
// Put a friendly message on the terminal
console.log('Server running at http://127.0.0.1:' + port + '/');
//END JS File

Output to terminal (from console.log(typeof d)):
