globalThis is not defined when adding angularfire modules to Angular Universal app

[chrisoppedal]

Angular version : 11.0.4

Firebase: Latest
AngularFire: version 6.1.4

Node version: 12.18.3

I started a new project with these commands:
ng new testProject
ng add @nguniversal/express-engine
ng add @angular/fire
ng deploy

• The project works with ng serve and ng deploy
• add an AngularFire module (AngularFireAuthModule) to app.module.ts
  ng deploy
• The app runs locally with ng serve but ng deploy fails to publish the 'ssr' function because of 'globalThis is not defined' error in firebase function logs.

This problem (globalThis is not defined...) is solved if you use Node V14 LTS version. I have the same problem when I use Node 10 or Node 12. Good luck!
