使用 *ngFor 我能夠渲染數(shù)據(jù)，但它會拋出此錯誤

錯誤 錯誤：NG0900：嘗試比較「[object Object]」時發(fā)生錯誤。僅允許數(shù)組和可迭代物件

這是我的服務(wù)方法

async getEditions(): Promise<Observable<Cigales>> {
    return this.http.get<Cigales>(url+"/candidates/editions", httpOptions).pipe(
      tap((getEditions: Cigales) => this.log('getEditions' + getEditions)),
      catchError(this.handleError<Cigales>('getEditions'))
    );
  }

這是我的元件方法

editions: Cigale[] = [];

  async getEditions(): Promise<void> {
    await this.CigalesService.getEditions().then(res=> {
      res.subscribe(data => {
        this.editions = [];
        this.editions = data.content;
      })
    })
  }

這是我的 Cigales 介面

export interface Cigales {
  content: Array<Cigale>,
  pageable: pageable,
  last: string;
  totalPages: string;
  totalElements: string;
  size: string;
  number: string;
  sort: sort;
  first: string;
  numberOfElements: string;
  empty: string;
}

export interface Cigale {
  id?: string;
  eventName: string;
  eventStartDate: string;
  eventEndDate: string;
}

type sort = {
  empty: boolean,
  sorted: boolean,
  unsorted: boolean
}

type pageable = {
  sort: sort,
  offset: string;
  pageNumber: string;
  pageSize: string;
  paged: string;
  unpaged: string;
}

這是我的 component.html

<tr *ngFor="let item of editions">
        <td>{{item.eventName}}</td>
        <td>{{item.eventStartDate}}</td>
        <td>{{item.eventEndDate}}</td>
        <td>
          <a class="d-inline" role="button" data-bs-toggle="modal" data-bs-target="#application-modal"><i class="bi bi-clipboard"></i></a>
          <a class="d-inline" role="button" data-bs-toggle="modal" data-bs-target="#application-modal"><i class="bi bi-pencil-square"></i></a>
        </td>
      </tr>

Console.log(this.editions) 和我得到兩個物件的陣列

控制臺結(jié)果

編輯：我嘗試過 Array.isArray(this.editions) 並且它回傳 true
