ng build prod 不返回模型字段

Question

我发现我的项目使用 ng serve 在我的本地机器上运行良好，但是当我使用 ng build prod 时它不返回模型字段

我使用由 api node.js 填充的以下模型

export class Tenders {
    public licitacion: string
    public fecha: string
    public finaliza: string
    public producto: number
    public descrip: string
    public cantidad: number
    public unidad: string
    public costo: number
    public ultcompra: string
    public proveedor: number
    public provenom: string
    public estado: number
}

我使用下面的代码来填充表格。

  async pedirTenders(user) {
    if (user) {
      // console.log('Tenders')
      this.tenderService.getTenders()
      .subscribe((resp: Tenders[]) => {
        console.log(resp.Tenders)
        this.dataSource.data = resp.Tenders
        this.dataSource.sort = this.sort
        this.dataSource.paginator = this.paginator
        this.table.dataSource = this.dataSource
      })
    }
  }

GetHTTP 服务

 getActives(): Observable<Tenders[]> {
    return this.http.get<Tenders[]>(this.url.baseApiUrl + 'tendersactives', this.getHttpOptions())
  }

当我在本地机器上运行 ng serve 时，它​​会返回 licitacion 字段，因为它在模型中声明 并且可以在下面的控制台屏幕截图中看到

with ng serve

但是当我运行 ng --prod 时，licitacion 字段不会像下面的屏幕截图那样显示

with ng --prod

两个请求使用的api是一样的

package.json 使用的是

提前感谢您的任何建议

亲切的问候

感谢大家花时间回答我。 但是，将 await 添加到异步请求后并不能解决问题。 我已经更改了 get 函数，但仍然缺少“licitacion”字段和所有与报价相关的文件

async pedirTenders(user) {
    if (user) {
      let resp: any = await this.tenderService.getTenders().toPromise()
      
      console.log(resp.Tenders)
      this.dataSource.data = resp.Tenders
      this.dataSource.sort = this.sort
      this.dataSource.paginator = this.paginator
      this.table.dataSource = this.dataSource
    }

这里是请求的 Html 代码。我正在尝试制作一个带有显示优惠子查询的折叠行的垫子表。 电线的东西，它在我的本地机器上一切正常，但在生产环境中却不行。

再次感谢
