So I'm making a converter app with ffmpeg, and it with convert the file and so I will save that file into a folder called converted.

so after it gets converted I try and download it using a the path of the converted file it would be like converted/convert.file format selected by user*

and I get this error

I'm trying to do this through renderer to main from a stackoverflow question here

renderer:

const ipc = require("electron").ipcRenderer;
const fs = require("fs");
const proc = require("child_process")
const $ = require("jquery");
const randomString = require("random-string");

const btn = document.getElementById("upload");
const selected = document.getElementById("format");
const info = document.getElementById("info");
let pp = document.querySelector(".pp");
let img = document.createElement("img");
let down = document.createElement("div");
down.innerHTML = "Your converted file has been downloaded to your <span>Downloads</span folder";
img.id = "previ";


var format = 'png';
var dir = "./converted"

selected.addEventListener("change", () => {
    var text = selected.options[selected.selectedIndex].text;
    format = text;
})

btn.addEventListener("click", (event) => {
    ipc.send("open");
});

var randID = randomString()

ipc.on("selected-file", (event, paths) => {
    if(info.hasChildNodes()) {
       $(down).detach();
    }
    $(info).append(`<div id=${randID} class="alert alert_succ"><span>${paths}</span> is being converted :)</div>`);
    if(!fs.existsSync(dir)) {
        fs.mkdirSync(dir)
    }

    //converter using ffmpeg command
    proc.exec(`ffmpeg -i "${paths}" converted/convert.${format}`, function(error, stdout, stderr) {
        img.src = `converted/convert.${format}`;
        pp.appendChild(img);

        ipc.on("saved", () => {
            fs.rmSync(dir, { recursive: true, force: true });
        });
        ipc.send("save", `converted/convert.${format}`)
        ipc.send("download", {
            url: dir + `convert.${format}`,
            properties: {directory: "Downloads"}
        });

        ipc.on("download complete", (event, file) => {
            console.log(file); // Full file path
        });
        $(info).append(down);

        $(`#${randID}`).detach();

        if(error !== null) {
            console.log(error);
        }
    })
})
