I am working on an Angular 6 project. This is the error I get when I build with --prod flag, host and run. I've been sitting on this for a long time. Initially thought it was probably a problem with the firestore package and i waited. But now updated to firestore 5.0.4, the problem still exists.

这通常表明您的设备当前没有正常的Internet连接.客户端将以脱机模式运行，直到能够成功连接到后端为止.

This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.

app.module.ts

app.module.ts

Imports: [
    AngularFireModule.initializeApp(environment.firebaseConfig),
    AngularFirestoreModule
]

app.component.ts

app.component.ts

constructor(public afAuth: AngularFireAuth,
          private afs: AngularFirestore,
          private db: AngularFireDatabase) {
    this._currentUser = this.afAuth.authState
      .pipe(
        switchMap((user: any) => {
           if (user) {
            console.log(user);
            return this.afs.collection('users').doc<User>(user.uid).valueChanges();
           } else {
             return Observable.create(null);
           }
        })
      );
}

仅供参考:身份验证仍然有效.

FYI: Authentication still works.
