Nodejs not sending http requests inside File ReadStream - node.js

Question

I'm having a very strange error where my http requests aren't sending at all. Once I send the request it just stops executing. I'm ingesting a CSV file through a ReadStream and sending requests inside the emitter listening blocks. If I try to send the request outside the emitters it can send fine, but I need to POST data from the file so it has to be sent within them (unless there's a way to export the data I don't know about.
Code:
const buffer = multipart.parse(event, true).fileName.content;
const file = stream.Readable.from(buffer);
let events;
file.pipe(csv())
.on('data', (data) => results.push(data))
.on('end', () => {
events = parseEvents(event, results);
console.log("sending request");
request({method: 'POST', url: 'https://httpbin.org/anything', json: {hello: 'world'}}, function (err, response, body) {
console.log(err);
console.log(response);
console.log(body);
});
console.log("finished request");
})
.on('error', error => {
console.log(error);
});
Before you say, I've also tried all kinds of requests. Using got, Axios, and request I've done awaits and tried to process it that way. I actually can get the promise but if I await it nothing happens. It's also not stuck in an infinite loop or anything because when put in a for loop it tries it every time and just always returns nothing.
For more info: The console gets the "sending request" log and then "finished request" and that's it. If I go the promise route, it doesn't even log the "finished request".

Per the documentation, url is not an option for http.request(), nor is json:

This seems like an async issue. After you fire your request, your code executes the next line rather than waits for the response and thats why you see the logs for sending and finished. Not sure how you implemented the promise solution before, and without seeing the rest of your code it would be hard to debug but I assume something like this should work.
return new Promise((resolve, reject) => {
file.pipe(csv())
.on('data', (data) => results.push(data))
.on('end', () => {
events = parseEvents(event, results);
console.log("sending request");
request({method: 'POST', url: 'https://httpbin.org/anything', json: {hello: 'world'}}, function (err, response, body) {
console.log(err);
console.log(response);
console.log(body);
resolve(body);
});
console.log("finished request");
})
.on('error', error => {
reject(error);
console.log(error);
})
});
Then wherever you are returning the promise to you can call .then(() => { //do stuff })
