Electron-builder: Error: Application entry file "main.js" in the ".../Contents/Resources/app.asar" does not exist. Seems like a wrong configuration.

"electron": "^2.0.2",
"electron-builder": "^20.15.1",
"electron-webpack": "^2.1.2"

I'm following this gist:
https://gist.github.com/matthewjberger/6f42452cb1a2253667942d333ff53404

Everything is ok, development is ok, but on yarn dist
I get this error:

Error: Application entry file "main.js" in the ".../Contents/Resources/app.asar" does not exist. Seems like a wrong configuration.

I found somewhere a workaround as add "extends": null in build in package.json but I get a compiled file (.app) that open a white page.
If I start the electron app created that shows only a white page with the inspector opened I see app.js not found error

My package.json build right now is:

"build": {
      "appId": "com.electron.electron-with-create-react-app",
      "win": {
          "icon": "https://cdn2.iconfinder.com/data/icons/designer-skills/128/react-256.png"
      },
      "directories": {
          "buildResources": "public"
      }
  },

I've tried to copy my src/electron-starter.js into main.js (into main project directory) and in src/main.js and into public/main.js as a workaround but the error is still there.

Do you have any hint?
Do I have to post something more about my actual project?

Add "files" field to your package.json
in my case "electron-starter.js" is electron entry file

"main": "./src/electron-starter.js",
  "homepage": "./",
  "build": {
    "appId": "oneoften",
    "files": [
      "./build/**/*",
      "./src/electron-starter.js"
    ],
    "dmg": {
      "contents": [
        {
          "x": 110,
          "y": 150
        },
        {
          "x": 240,
          "y": 150,
          "type": "link",
          "path": "/Applications"
        }
      ]
    },
    "linux": {
      "target": [
        "AppImage",
        "deb"
      ]
    },
    "win": {
      "target": "squirrel",
      "icon": "build/favicon.ico"
    },
    "directories": {
      "buildResources": "assets"
    }
  },

~~I'm seeing this as well. It's only happening in CI, on both Windows and macOS.~~

~~It works in development in both environments, as well as when run manually in the CI environments. But when running it through Gitlab CI, I'm seeing this error.~~

~~Even better, with the exact same setup, just in a different branch name, it works fine.~~

Yeah I totally had the build phase commented out.

How did you solve your issue?

I'm trying this and it works. electron-builder need build folder in the package.
i have src/main.js and no build machanicm for my app to generate build like react-script.

so what work is to let the EB to know what directory is use as build folder by using files key in package.json.

"files": [
     "node_modules/**/*",
      {
           "from":"src",
           "to":"build",
           "filter":"**/*"
       }    
],

p.s I'm new to EB too I don't know if it work for everyone.
