Twig template for custom entity not working

Question

I created a custom entity (Representative) using the Drupal Console generate:entity:content command.

The entity works correctly. I added fields, added some content, and I can query this entity.

My problem is that I can't render this entity in a template file, using the following code.

$build = [
  '#theme' => 'representatives',
  '#representative_entity' => $representative
];

I get the following error.

Exception: Object of type Drupal\kelk_representatives\Entity\RepresentativeEntity cannot be printed. in Drupal\Core\Template\TwigExtension->escapeFilter() (line 476 of core/lib/Drupal/Core/Template/TwigExtension.php).

Can anyone help?

You need to use the entity view builder, to correctly render an entity, like the following code.

$view_builder = \Drupal::entityTypeManager()
  ->getViewBuilder('representatives');
$entity_view = $view_builder->view($representative);

$build = [
  '#theme' => 'representatives',
  '#representative_entity' => $entity_view,
];
