I'm trying to create a paragraphs field on a node programmatically. This is what I've found for Drupal 7: https://drupal.stackexchange.com/questions/188192/how-to-create-paragraphs-item-programmatically , but that is not working for me in Backdrop. Here is the error I receive:
Error: Call to undefined function entity_save() in ParagraphsItemEntity->save() (line 429 of /app/web/modules/contrib/paragraphs/ParagraphsItemEntity.inc). Drush command terminated abnormally due to an unrecoverable error.
