Module not found: Can't resolve 'react-dom/lib/DOMLazyTree'

[noav-cp]

When I add the line
import { launch } from '@extjs/reactor';
to my index.js file, I immediately get the following error:

./node_modules/@extjs/reactor/dist/ExtJSComponent.js
Module not found: Can't resolve 'react-dom/lib/DOMLazyTree' in 'C:\Users\myUser\Documents\React\smb-react\node_modules@extjs\reactor\dist'
The app doesn't load.

Environment:

• reactor version: 1.1.2
• sencha-cmd version: 0.1.4
  I'm using Chrome version 90.0.4430.212 on Windows 10 Pro.
