latest.yml not created

• electron-builder version: 19.7.1
• electron-updater version: 1.16.0
• Target: x64 windows NSIS (using the docker container)

After building several times, each time increasing the app version number, my dist/ folder looks like this:

$ ll dist/
total 232M
-rw-r--r-- 1 root root  44M Jun 21 14:56 infinity-vault Setup 1.0.0.exe
-rw-r--r-- 1 root root  88M Jun 21 15:01 infinity-vault Setup 1.0.1.exe
-rw-r--r-- 1 root root 101M Jun 21 15:41 infinity-vault Setup 1.0.2.exe
drwxr-xr-x 4 root root 4.0K Jun 21 15:39 win-unpacked/

Notice, there is no latest.yml. I just upgraded to 19.7.1 today, and earlier today I was getting the latest.yml. There is also no app-update.yml in the win-upacked/resources folder.

I find it strange that each of the installer files is larger than the previous one.

My build config:

"use strict";

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

let t_linux = Platform.LINUX.createTarget();
let t_windows = Platform.WINDOWS.createTarget();

let win_config = { 
  appId: 'com.testapp.sr',
  productName: 'InfinityVault',
  artifactName: "${productName}-Setup-${version}.${ext}",
  win: {  target: ['nsis']  }, 
  nsis: { artifactName: "${productName}-Setup-${version}.${ext}" } };

let linux_config = { appId: 'com.testapp.sr',
  productName: 'infinityvault',
  linux: { target: 'deb' } };

let app_config = { 
  targets: t_windows,
  config: win_config,
  artifactName: "${productName}_Setup_${version}.${ext}",
  publish: [{ provider: "generic", url: "http://10.1.10.187:8080/" }]

};
builder.build(app_config).then(data => {
  console.log('got here', data);
}).catch(error => {
  console.log('error', error.message.slice(0, 150));
});

(sorry about all the artifactName elements, that doesn’t work either…)
