TypeError: Cannot read property 'stringify' of undefined

Bug Report

What is the current behavior?

server.ts

(global as any).WebSocket = require('ws');
(global as any).XMLHttpRequest = require('xhr2');

import 'zone.js/dist/zone-node';
import { enableProdMode } from '@angular/core';
// Express Engine
import { ngExpressEngine } from '@nguniversal/express-engine';
// Import module map for lazy loading
import { provideModuleMap } from '@nguniversal/module-map-ngfactory-loader';

import * as express from 'express';
import { join } from 'path';

// Faster server renders w/ Prod mode (dev mode never needed)
enableProdMode();

// Express server
const app = express();

const PORT = process.env.PORT || 4000;
const DIST_FOLDER = join(process.cwd(), 'dist/browser');

const domino = require('domino');
const fs = require('fs');
const path = require('path');
const template = fs.readFileSync(path.join(__dirname, join(DIST_FOLDER, 'index.html'))).toString();
const win = domino.createWindow(template);
global['window'] = win;
global['document'] = win.document;

// * NOTE :: leave this as require() since this file is built Dynamically from webpack
const { AppServerModuleNgFactory, LAZY_MODULE_MAP } = require('./dist/server/main');

// Our Universal express-engine (found @ https://github.com/angular/universal/tree/master/modules/express-engine)
app.engine('html', ngExpressEngine({
    bootstrap: AppServerModuleNgFactory,
    providers: [
        provideModuleMap(LAZY_MODULE_MAP)
    ]
}));

app.set('view engine', 'html');
app.set('views', DIST_FOLDER);

// Example Express Rest API endpoints
// app.get('/api/**', (req, res) => { });
// Serve static files from /browser
app.get('*.*', express.static(DIST_FOLDER, {
    maxAge: '1y'
}));

// All regular routes use the Universal engine
app.get('*', (req, res) => {
    res.render('index', { req });
});

// Start up the Node server
app.listen(PORT, () => {
  console.log(`Node Express server listening on http://localhost:${PORT}`);
});

I’m using angular material. And I added these lines of code from another issue because of window is not defined error. When I run “npm run build:ssr” no error occurs. But when I run “npm run serve:ssr” gives me an error. Added code:

const domino = require('domino');
const template = fs.readFileSync(path.join(__dirname, join(DIST_FOLDER, 'index.html'))).toString();
const win = domino.createWindow(template);
global['window'] = win;
global['document'] = win.document;

Error:

TypeError: Cannot read property 'stringify' of undefined

[satya5561]

i am also facing same issue

I have fixed this issue by uninstalling firebase and related plugins.

[philip-firstorder]

Also had this today, and I fixed it by updating node version from 10 to 12.

I had 2 environments: local, with docker using node:12 <= this worked dev, with docker using node:10 <= this gave the error

So I updated my dev environment to use node:12 and the error was gone.

I also use Angular 8 + Material + Firebase + Universal + Prerender.ts + webpack + domino
