I am following this ‘getting started’ page. Integrating Pages - Builder.io

But I get errors.

Hello @heydenb,

Welcome to the builder.io forum post!

Would you be able to share the code for the landing-page.component.html?

Below is an example that works well for us

<builder-component
  *ngIf="!noBuilderPageForUrl"
  model="page"
  (load)="noBuilderPageForUrl = $event ? false : true"
  (error)="noBuilderPageForUrl = true"
  [content]="builderRSP | async"
>
  <!-- Default content inside the tag shows while the builder content is fetching -->
  <div class="spinner"></div>
</builder-component>
<app-page-not-found *ngIf="noBuilderPageForUrl"> </app-page-not-found>
