The URL is wrong, this tries to download an ECS release from the official Electron repo. When you are packaging with something like electron-builder you need to set at mirror to get the correct URL. Check out this FAQ: https://github.com/castlabs/electron-releases/wiki/FAQ#how-can-i-use-electron-builder-with-ecs

[iamharshitpandeyy]

So we have to add it to our package. json NodeJS, right ? Do we have to add something after the "v" in the string "https://github.com/castlabs/electron-releases/releases/download/v" like version ?

[khwaaj]

Yeah, you need to add It to your package.json, more details are available in the electron-builder documentation if you need it. You should not have to add extra after download/v, this is just the first part of the URL that is used to assemble the final one so the version will be attached automatically.

Still It's was not building, showing same issue

[khwaaj]

That should work in general, maybe you have some conflicting state or configuration?

For example this package.json from a quick start project works fine:

{
  "name": "electron-quick-start",
  "version": "1.0.0",
  "description": "A minimal Electron application",
  "main": "main.js",
  "scripts": {
    "start": "electron .",
    "dist": "electron-builder"
  },
  "repository": "https://github.com/electron/electron-quick-start",
  "keywords": [
    "Electron",
    "quick",
    "start",
    "tutorial",
    "demo"
  ],
  "author": "GitHub",
  "license": "CC0-1.0",
  "devDependencies": {
    "electron": "github:castlabs/electron-releases#v29.1.5+wvcus",
    "electron-builder": "^24.9.1"
  },
  "build": {
    "electronDownload": {
      "mirror": "https://github.com/castlabs/electron-releases/releases/download/v"
    }
  }
}
