UnhandledPromiseRejectionWarning: TypeError: settings.anyMethod is not a function

See original GitHub issue

Hello,

I’m currently updating Electron Settings from 3.2.0 to 4.0.1 and I got many issues. I was able to update my codebase based on the docs but when I’m trying to call any method, I get that UnhandledPromiseRejectionWarning telling me something is not a function where it should be.

Part of my code:

const settings = require('electron-settings');
// ...

function createWindow() {
    // default
    let version = "v0.1";
    // ...
    console.log(settings);
    settings.configure({
        dir: __dirname,
        fileName: 'settings.json'
    });
    const exists = settings.hasSync('test');
    console.log(exists);
    if (settings.hasSync('version'))  {
        version = settings.getSync('version');
    }
    // ...
}

Full output (example):

$ npm start

> TestProject@0.0.1 start <<Path>>\src\main\electron
> electron .

  }

I think I made a tiny mistake but I’m not able to figure out… I hope that you can help me.
