Error encountered while rendering content in an Angular template

I'm currently integrating ngx-carousel into my application.

Interestingly, the carousel works perfectly when I manually input the data. However, when trying to fetch the data from the server, it fails to work as expected.

Take a look at my code snippet below:

this.contentfulService.getContent('ourSpecialties')
  .then(ourSpecialties => {
    this.ourSpecialties = ourSpecialties;
    console.log(this.ourSpecialties);
  });

HTML

<owl-carousel-o *ngIf="ourSpecialties" [options]="customOptions">
  <ng-template *ngFor="let ourSpecialtie of ourSpecialties" carouselSlide>
    <img src="{{ourSpecialtie.fields.image.fields.file.url}}">
    <h3>{{ourSpecialtie.fields.title}}</h3>
    <p>{{ourSpecialtie.fields.description}}</p>
  </ng-template>

</owl-carousel-o>

The data is successfully logged in the console for ourSpecialties.

Please advise on what could be causing the issue here?

Answer №1

*ngFor directive microsyntax has now been transformed to include an outer <ng-template> tag. It appears that the inner template is not being displayed properly. To resolve this issue, consider enclosing the *ngFor within a <ng-container> tag. Here is a suggested implementation:

<owl-carousel-o *ngIf="ourSpecialties" [options]="customOptions">
  <ng-container *ngFor="let ourSpecialtie of ourSpecialties">
    <ng-template carouselSlide>
      <img src="{{ourSpecialtie.fields.image.fields.file.url}}">
      <h3>{{ourSpecialtie.fields.title}}</h3>
      <p>{{ourSpecialtie.fields.description}}</p>
    <ng-template>
  </ng-container>
</owl-carousel-o>

Ensure that the data structure being sent from the server is consistent. Is it being received as an array or an Iterable object?
