Bug Report

I got error 400 Bad Request; when posting a photo.

here is the simpliest code

const fs = require('fs');
const util = require("util");
const insta = require("instagram-private-api");


const readFileAsync = util.promisify(fs.readFile);

const path = './screenshot.png';


const ig = new insta.IgApiClient();

ig.state.generateDevice(username);


( async () => {


let g = await ig.account.login(username, password);
console.log(g);
console.log("logged in!")

const publishResult = await ig.publish.photo({
    file: await readFileAsync(path),
    caption: 'my caption',
  });

})();

The logging seems to work since console.log(g), print out formated dict.
screenshot.png is in 1080 × 1080.
I'm using Node.js v21.5.0.

full print of the error:

One potential cause of this error could be related to how the image file is being uploaded. your code uses util.promisify(fs.readFile) to read the image file asynchronously, which may not handle binary data correctly, especially if the file is large or in a format that Instagram's API doesn't accept properly.

const { get } = require('request-promise');

  const imageBuffer = await get({
      url: imgeurl,
      encoding: null, 
  });

  await ig.publish.photo({
      file: imageBuffer,
      caption: 'my caption',
  });

Try this and let me know

screenshot.png is in 1080 × 1080

Pretty sure you need to upload JPEG.
