筛选observable的响应并保存到本地变量

我有一个返回ApiResponse对象的服务，其中结果是Client对象的向量。该服务运行良好，数据正确接收。问题是，在我想要呈现信息的组件中，我需要过滤该服务的结果以在两个部分中显示它们，但由于滤波后的矢量始终为空，因此这是不可能的。另一方面，我不明白的是，为什么当我尝试在OnInit中为每个控制台显示矢量客户端时，它会将其返回为空，但如果它获取数据并显示它，则会在模板中使用它。筛选observable的响应并保存到本地变量

这是我的代码：

export class PartnersExpirationsComponent implements OnInit { 
    expirations: Client[] = []; 
    expirationsWithoutDays: Client[] = []; 
    expirationsWithDays: Client[] = []; 

    constructor(
    private partnersExpirationsService: PartnersExpirationsService 
) { } 

    ngOnInit() { 
    this.getData(); 
    } 

    private getData(): void { 
    this.partnersExpirationsService.getClients() 
     .subscribe(
     next => { 
     console.log(next); 
     this.expirations = next.results; 
     this.expirationsWithoutDays = this.expirations.filter(client => { 
      return client.extraDays === false; 
     }); 
     this.expirationsWithDays = this.expirations.filter(client => { 
      return client.extraDays === true; 
     }); 
     }, 
     error => this.handleError 
    ); 
    } 
}

事情我经历，我并没有意识到？

编辑：这是控制台打印时它返回下一个模型：

export interface IARClient { 
    info: { 
     results: number, 
     version: string, 
    }; 
    results: Client[]; 
} 

export class Client { 
    constructor(
     public name: string, 
     public lastName: string, 
     public numberDni: number, 
     public email: string, 
     public street: string, 
     public phone: number, 
     public alternatePhone: number, 
     public birthdate: Date, 
     public dateRegister: Date, 
     public balance: number, 
     public extraDays: boolean, 
     public district: District, 
     public state: State, 
     public gender: Gender, 
     public associationXClient: AssociationXClient, 
     public id?: number, 
    ) { } 
}
