Publishing an electron application fails with: Error!! TypeError: Cannot read property 'provider' of null

Question

I'm trying to publish my Electron application, so, I added publish to package.json and now it looks like this:

{
  "devDependencies": {
    "electron": "^1.7.4",
    "electron-builder": "^11.5.1"
  },
  "dependencies": {
    "electron-publisher-s3": "^19.16.0"
  },
  "build": {
    "appId": "tech.dashman.Dashman",
    "win": {
      "icon": "build/icon.ico"
    },
    "publish": [
      {
        "provider": "s3",
        "bucket": "dashman-app",
        "path": "/",
        "acl": "public-read"
      }
    ]
  }
}

I have a separate app/package.json. When I try to publish by running

node build\dist.js

I get

Rebuilding native production dependencies for win32:ia32

build\dist.js contains something like this:

const builder = require("electron-builder");
const Platform = builder.Platform;
const Arch = builder.Arch;

const fs = require("fs");

builder.build({
    targets: Platform.WINDOWS.createTarget("nsis", Arch.ia32),
    config: {
        "afterPack": () => { do_some_stuf()});
        }
    }
}).then(() => {
    console.log("Done!");
}).catch((error) => {
    console.log("Error!!", error);
});

Any ideas why am I getting that error?

Answer 1

The problem seemed to be in that I was running a very old version of electron-builder. I upgraded and now it's working.
