How to upload file from the back-end to another back-end? - node.js

Question

I am trying to upload file from another back-end to currently existing API.
For doing so, I am trying to replicate what's being done in the front-end.
To create FormData and then send it to the API.
But the request seems to hang...
And if I would try to replicate the request express would console log error
Error: Request aborted
at IncomingMessage.<anonymous> (C:\Users\TCP_BCP\node_modules\formidable\lib\incoming_form.js:122:19)
at IncomingMessage.emit (events.js:314:20)
at IncomingMessage.EventEmitter.emit (domain.js:506:15)
at abortIncoming (_http_server.js:533:9)
at socketOnEnd (_http_server.js:549:5)
at Socket.emit (events.js:326:22)
at Socket.EventEmitter.emit (domain.js:483:12)
at endReadableNT (_stream_readable.js:1241:12)
I understand that if I am trying to perform new request the old one gets aborted probably.
But why the request could hang? The target file is small in size (500kb +-).
In the front-end there would be used $(".form").ajaxSubmit
In the back-end I am trying to create form with FormData.
What could be wrong?

So the issues was with headers.
Formidable at other API would hang without passing FormData headers for axios.
Code bellow allowed me to successfully upload files to a other API.
const data = await fs.readFile(zipPath);
const form = new FormData();
form.append("file", data, zipName);
const headers = form.getHeaders();
Axios.defaults.headers.cookie = cookies;
await Axios({
method: "POST",
url: endpoint,
headers: {
...headers,
cookie: cookies,
},
data: form,
});
