Angular 错误：未捕获（承诺中）：类型错误：无法读取属性'；状态'；空的

我正在尝试将票证的JSON结果从打开过滤到关闭，并且正在进行中，JSON数据从api正确返回，并保存在

totalTicketsDataMain

变量中。但每当我尝试过滤数据时，存储

openTicketsData

的变量就会在mozilla上抛出错误

电话号码是98

this.openTicketsData = this.totalTicketsDataMain.filter(x => (x.status === "Open" || x.status === "In Progress")); //line 98

我不确定我遗漏了什么或做错了什么这是我的TicketlistComponent

openTicketsData: Ticket[];
  totalTicketsDataMain: Ticket[];

status = "Open";
 async ngOnInit(): Promise<void> {
       await this.getTicketsData();
  }

 async getTicketsData(): Promise<void> {
    this.totalTicketsDataMain = await this.ticketService.getTickets(this.currentProjectId);
    if (this.teamId && this.eaId && this.householdId) {
      this.totalTicketsDataMain = this.totalTicketsDataMain.filter(x => x.eaId == this.eaId && x.householdId == this.householdId && x.teamId == this.teamId && x.status == this.status);
    }

    if (this.totalTicketsDataMain) {
      this.openTicketsData = this.totalTicketsDataMain.filter(x => (x.status === "Open" || x.status === "In Progress")); //line 98
      this.inProgressTicketsData = this.totalTicketsDataMain.filter(x => (x.status === "In Progress"));
      this.closedTicketsData = this.totalTicketsDataMain.filter(x => (x.status === "Closed"));
      let user =  this.userSessionService.getSession('usersession') as UserSession;
      this.assaignedToMeTicketsData = this.totalTicketsDataMain.filter(x => x.assignedTo == user.emailId);
      this.createdByMeTicketsData = this.totalTicketsDataMain.filter( x=> x.createdBy == user.emailId);
    }

    if (this.teamId == undefined  || this.eaId == undefined || this.householdId == undefined) {
      this.totalTicketsData = this.totalTicketsDataMain.filter(x => x.status == "Open" || x.status == "In Progress");
    }


  }

openTicketsData:Ticket[]；
totalTicketsDataMain：票证[]；
status=“打开”；
异步ngOnInit（）：承诺{
等待此消息。getTicketsData（）；
}
异步getTicketsData（）：承诺{
this.totalTicketsDataMain=等待this.ticketService.getTickets（this.currentProjectId）；
if（this.teamId&&this.eaId&&this.householdId）{
this.totalTicketsDataMain=this.totalTicketsDataMain.filter（x=>x.eaId==this.eaId&&x.householdId==this.householdId&&x.teamId==this.teamId&&x.status==this.status）；
}
if（this.totalTicketsDataMain）{
this.openTicketsData=this.totalTicketsDataMain.filter（x=>（x.status==“打开”| | x.status==“正在进行”）；//第98行
this.inProgressTicketsData=this.totalTicketsDataMain.filter（x=>（x.status==“进行中”）；
this.closedTicketsData=this.totalTicketsDataMain.filter（x=>（x.status==“Closed”）；
让user=this.userSessionService.getSession（'usersession'）作为usersession；
this.assignedtometicketsdata=this.totalTicketsDataMain.filter（x=>x.assignedTo==user.emailId）；
this.createdByMeTicketsData=this.totalTicketsDataMain.filter（x=>x.createdBy==user.emailId）；
}
if（this.teamId==未定义| | this.eaId==未定义| | this.householdId==未定义）{
this.totalTicketsData=this.totalTicketsDataMain.filter（x=>x.status==“打开”| | x.status==“进行中”）；
}
}

取票服务功能

async getTickets(projectId: string): Promise<Ticket[]> {
        try {
            const url = ServiceConstants.apiUrl + `/tickets/getticketlist?projectId=${projectId}`;
            let response = await this.httpService.get(url, { headers: this.getHeaders() }).toPromise();
            return response as Ticket[];
        } catch (error) {
            this.handleError(error);
        }
    }

异步getTickets（projectd:string）：Promise{ 试一试{ 常量url=ServiceConstants.apiUrl+`/tickets/getticketlist？projectId=${projectId}`； 让response=wait this.httpService.get（url，{headers:this.getHeaders（）}）.toPromise（）； 返回响应作为票证[]； }捕获（错误）{ 此.handleError（错误）； } }

如果前两个If条件不符合，则this.totalTicketsDataMain将保持为空。尝试获取此.totalTicketsData将是不可能的。此外，如果没有遵循所有条件，则没有状态设置为打开。

在此处输入code

因为

x

为null，并且null没有

状态

属性，您必须调试并找出为什么在loopHi@Rumjhum Singru中x变为null我不明白您的意思。totalTicketsDataMain为null，这不是您的if条件已满足的情况。@arriff但当我做控制台日志时，它有数据，

this.totalTicketsDataMain=wait this.ticketService.getTickets（this.currentprojectd）；console.log（“data is thre”，this.totalTicketsDataMain）

，它打印数据您介意在第98行显示您的控制台日志吗，就在筛选之前。如果共享，数据可用

openTicketsData: Ticket[];
  totalTicketsDataMain: Ticket[];

status = "Open";
