Description Not able to update my squirrel electron application

Steps to recreate

1. install the .exe file
2. wait for 6000 seconds the electron checks for an update
3. then i get this error

Expected behavior it must have updated in the background

Actual behavior its throws an error

Additional information

I have electron.js file

const path = require("path");
const { app, BrowserWindow, ipcMain, autoUpdater } = require("electron");
const isDev = require("electron-is-dev");

if (!isDev) {
  if (require("electron-squirrel-startup")) return app.quit();
}

const server = "https://random-server.com";
const updateUrl = `${server}/update/${process.platform}/${app.getVersion()}`;

autoUpdater.setFeedURL({ url: updateUrl });

if (!isDev) {
  setTimeout(() => {
    autoUpdater.checkForUpdates();
  }, 60000);
}

function createWindow() {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    icon: "desktop-icons/icon.png",
    webPreferences: {
      preload: path.join(__dirname, "preload.js"),
      nodeIntegration: false,
      contextIsolation: true,
      enableRemoteModule: false,
    },
  });

  win.loadURL(
    isDev
      ? "http://localhost:3001"
      : `file://${path.join(__dirname, "./index.html")}`
  );

my backend hazel server is returning the Release file to update the squirrel application actually, my repository is private so I am using the hazel server as a proxy to server RELEASE files from my private repository to electron app

Your releases file is invalid - the 2nd item needs to be a filename, not an arbitrary URL. I would recommend simply uploading your files to a static file host (you can actually even use Vercel itself, which is great because you get HTTPS for free and a CDN) and not try to write your own RELEASES file
