导航堆栈至少需要一个根页面 - 离子

我尝试在这样的函数中使用setRoot ionic导航控制器:

async login(userx: User1){
    // push another page on to the navigation stack
    // causing the nav controller to transition to the new page
    // optional data can also be passed to the pushed page.
    /**/

    if(!userx.email || !userx.password) {
      alert("You need to enter an email and password");
    }
    else if(this.stylist && this.type == 'user') {
      alert("You do not have a stylist account, you can add one using the signup page");
    }
    else if(this.users && this.type == 'stylist') {
      alert("You do not have a user account, you can add one using the signup page");
    }
    else if(!this.users && !this.stylist) {
      alert('You need to select "Hair Stylist" or "User"');
    }
    else {
      this.afAuth.auth.signInWithEmailAndPassword(userx.email, userx.password).then((data) => {
        console.log(data);
        if(data.email && data.uid) {
          if(this.stylist) {
            this.storage.set('type', 'user/stylist/stylist');
            this.storage.set('loggedin', true);
            this.navCtrl.setRoot(FeedStylist);

          }
          else {
            this.storage.set('type', 'user/stylist/user');
            this.storage.set('loggedin', true);
            this.navCtrl.setRoot(FeedUser); 
          }
        }
      }).catch((e) => {alert("The username or password is incorrect")});
    }
  }

它可以工作但是还有一个弹出运行时错误,上面写着:

Uncaught (in promise): navigation stack needs at least one root page

我不明白为什么它会在我设置root的命令上说这个。任何帮助将不胜感激。
