Image field and smart date problem

I’m not sure if you’re familiar with working with hooks, but I couldn’t find a way to map file uploads to Media directly. So, I used the hook_entity_presave() to handle that.

function mymodule_ENTITY_TYPE_ID_presave(EntityInterface &$entity) {
  // On webform creation, if the entity is a node of type,
  // create a media entity for the field_logo if it exists.
  // This is to ensure that the field_logo is a media entity.
  // This is a workaround for the fact that webforms do not support media
  // entities directly.
  // Get field_logo target_id.
  $field_logo = $entity->get('field_logo');
  $field_logo_value = $field_logo->getValue();
  $logo_entity_type = $field_logo->entity;
  // If logo_entity_type is empty, it's a new media from webform as presave 
  // from node add/edit will have the media entity already.
  if (isset($field_logo_value[0]['target_id']) && empty($logo_entity_type)) {
    // Get the file entity.
    $file = File::load($field_logo_value[0]['target_id']);
    if ($file) {
      // Create media entry.
      $media = Media::create([
        'bundle' => 'image',
        'name' => $file->getFilename(),
        'field_media_image' => [
          'target_id' => $file->id(),
          'alt' => $file->getFilename(),
        ],
        'field_caption' => $file->getFilename()
      ]);
      // Save the media entity.
      $media->save();
      $entity->set('field_logo', [
        'target_id' => $media->id(),
        'alt' => $file->getFilename(),
      ]);
    }
  }
}
