How to add term programmatically in Paragraph field? I have a paragraph with a taxonomy reference (autocomplete) field and I want to populate it when I create programmatically a pararagraph item.
I checked the option "Create referenced entities if they do not already exist" in this field.

I use this code, but I don't know how to find more informations to do that without Term::create (if it's possible) :

use Drupal\node\Entity\Node;
use Drupal\paragraphs\Entity\Paragraph;

        foreach ($field_value as $creator_type =&gt; $creator_name) {

            $paragraph = Paragraph::create(['type' =&gt; '_zotero_ref_creators']);
            //text field
            $paragraph-&gt;set('field_nom_prenom_createur', $creator_name);
            //taxo reference field
            $paragraph-&gt;set('field_type_createurs', $creator_type);

            //$paragraph-&gt;isNew();
            $paragraph-&gt;save();

            $paragraphn_field_value = array(
              'target_id' =&gt; $paragraph-&gt;id(),
              'target_revision_id' =&gt; $paragraph-&gt;getRevisionId(),
            );

            $node_reference-&gt;set('field_liste_contrib', $paragraphn_field_value);
          }
First load the node already created.
Second, create a paragraph like you did but for taxonomy term add "target_id" and for value choose a term id. 
Set the paragraph value to your field of type paragraph from node. Also you need to save the node.

    $node = Node::load($nid);    
     $paragraph = Paragraph::create([
            'type' =&gt; 'gallery_image',
            'field_type_createurs' =&gt; ['target_id' =&gt; $value],
          ]);
          $paragraph-&gt;save();

          $current[] = [
            'target_id' =&gt; $paragraph-&gt;id(),
            'target_revision_id' =&gt;$paragraph-&gt;getRevisionId(),
          ];

   $node-&gt;set('your_field', $current);
   $node-&gt;save();


Varible $value is a term id.

Hope to help you.
