我更新了我的angular-cli然后我在ng服务中出错了

 Callback was already called.
at throwError (node_modules\neo-async\async.js:14:11)
at node_modules\neo-async\async.js:2805:7
at _combinedTickCallback (internal/process/next_tick.js:131:7)
at process._tickCallback (internal/process/next_tick.js:180:9)

这是我的项目包的版本:

我试图删除节点模块然后重新安装但仍然有相同的错误...任何建议？

如何将“ [对象对象]”（日期选择器）转换为日期格式

<input type="text"
       id="date"
       class="form-control"
       formControlName="date"
       name="date"
       [(ngModel)]="date"
       ngbDatepicker
       #incorporatedDatePicker="ngbDatepicker"
       (click)="incorporatedDatePicker.toggle()"
       readonly>

当我展示

    {{meeting.date | date }} 

我有错误：管道'DatePipe'的invalidPipeArgument错误'[object Object]'

我必须获取当前用户 ID 才能在我的应用程序的不同部分使用它。

登录.component.ts：

onSignin(form: NgForm){
const UserName = form.value.UserName;
const Password = form.value.Password;
this.authService.signinUser(UserName,Password).map(res => res.json())
 .subscribe(
   data => {
     if (data.Id == 0){
     this.invalid=true;
    }
    else{
      localStorage.setItem('isLoggedin', 'true');
      this.router.navigate(['/calendar']);
      console.log('Ok');
   }})}

auth.service.ts：

signinUser(UserName,Password): Observable<any>{
  return this.http.get('http://api.##.com/api/security/signin?username='+UserName+'&password='+Password);
}

当我将日期发送到 API 时，如何使用打字稿以特定格式 (DateTime) 将当前日期发送到 API，它以这种格式发送，所以我收到了错误。

我的 ts 代码：

date: Date;
constructor( private dataStorageService: DataStorageService) {
    this.date = new Date();
}
onSubmit(Message , form : FormGroup){
    let newMsg = {
        username: Message.username,
        header: Message.header,
        content: Message.content,
        file: Message.file
    }
  this.dataStorageService.postMessage(newMsg, this.Id , this.date).subscribe(data => {
      console.log('done');
      console.log(this.date);
      }, error => {
          console.error("Error saving jobs!");
      })
}

http://api.azharcouncil.com/api/notification/PostNotification?user_id=15&Header=hj&Content=hjh&File_Path=null& date=Wed%20Nov%2015%202017%2010:44:56%20GMT+0200%20（和埃及%20 %20 时间）

所以我的请求由于日期格式而无效...
