[REQUIRED] Describe the problem

I’ve added firebase on a new Angular project and it works fine when I run ng serve. I can build the project for SSR without problem running the command npm run build:ssr. But when I run npm run serve:ssr I get the following error:

myapp@0.0.0 serve:ssr C:\Develop\js\projects\myapp
node dist/server

C:\Develop\js\projects\myapp\dist\server\main.js:126258
        throw new Error("package.json does not exist at " + package_json_path);
        ^

Steps to reproduce:

• Create a new Angular app
• Install firebase: npm install firebase –save
• Use firebase in the default AppComponent (like in the following section)
• Install nguniversal: ng add @nguniversal/express-engine –clientProject myapp
• Build the project for ssr: npm run build:ssr
• Run the project with ssr: run serve:ssr

Relevant Code:

export class AppComponent {

  constructor() {

    const app = firebase.initializeApp(environment.firebase);
    const db = firebase.firestore(app);

    db.collection('articles').get().then((querySnapshot) => {
      querySnapshot.forEach((doc) => {
          console.log(`${doc.id} => ${doc.data()}`);
      });
    });
  }
}
