Как уловить ошибку при аутентификации?

Как улавливать ошибку при аутентификации? Я получаю неприятную ошибку в консоли, когда хочу получить изящную ошибку для плохой аутентификации. Моя тревога за ошибки не будет показывать:Как уловить ошибку при аутентификации?

constructor(public af: AngularFire){ 

    this.af.auth.subscribe(user => { 
      console.log('---->', user) 
      if (user) { 
       this.user = user.auth.providerData[0]; 
       if (user.auth.emailVerified==false){ 
       user.auth.sendEmailVerification().then(function() { 
        alert('Email Verification Sent!'); 
       }); 
       } else { 
       this.router.navigate(['/dashboard']); 
       } 
    },error => { alert('dude whats up with this?') 

    }); 

} 



onSubmit(){ 

     console.log(this.email,this.password) 
     this.af.auth.login({ 
      email: this.email, 
      password: this.password, 
     }, 
     { 
      provider: AuthProviders.Password, 
      method: AuthMethods.Password, 
     }) 
    }

The login method возвращается обещание, так:

this.af.auth.login({ 
    email: this.email, 
    password: this.password, 
}, { 
    provider: AuthProviders.Password, 
    method: AuthMethods.Password, 
}) 
.catch((error) => { console.log(error); });

auth наблюдаемым используется для излучения изменений в состоянии аутентификации - не ошибки, возникающие при входе в систему и т. д.
