I'm trying to make a POST request to upload a binary to a server and the form data is not being sent correctly (or at all).

My current integration of node-fetch with puppeteer works fine for POST or GET requests with {"Content-Type": "application/json"}.

Here is my code:

const FormData = require("form-data");

const fetch = require("node-fetch");

const fs = require("fs");



upload(pkgUrl) {

  return new Promise(async (resolve, reject) => {



    const token = ...

    const url = ...



    const stats = fs.statSync(pkgUrl);

    const fileSizeInBytes = stats.size;

    console.log("fileSizeInBytes " + fileSizeInBytes); // Prints a valid size



    const form = new FormData();

    form.append("version", "1.0");

    form.append("appFile", fs.createReadStream(pkgUrl));

    form.append("minFirmwareVersion", 8164134);

    form.append("newPackage", true);



    let headers = form.getHeaders(); 

    headers["csrf-token"] = token;



    const response = await this._makeHTTPRequest(url, "POST", headers, form);



    (...)

  });

}



_makeHTTPRequest(url, method = "GET", headers = null, body = null, parse = true) {

  return new Promise(async (resolve, reject) => {

    try {

      const response = await this._page.evaluate(async (url, method, headers, body, parse) => {

        let request = {

          method: method,

          credentials: "include"

        };



        if (headers) {

          request["headers"] = headers;

        }



        if (body) {

          request["body"] = body;

        }



        // Make request

        const fetchResponse = await fetch(url, request);



        // Return parsed (object) or plain-text response

        return parse ? await fetchResponse.json() : await fetchResponse.text();

      }, url, method, headers, body, parse);



      resolve(response);

    } catch (error) {

      reject(error);

    }

  });

}

This is how the form data should be sent:

And this is how is being sent:

Also, the content-length being sent is only 15 bytes and it should be around 2mb.

Am I using form-data and node-fetch correctly?

Thanks!
