Having block_content installed and starting a search, leads to:
Error: Call to undefined method Drupal\block_content\Entity\BlockContent::getParentEntity() in Drupal\scanner\Plugin\Scanner\Paragraph->search() (Zeile 55 in /web/modules/contrib/scanner/src/Plugin/Scanner/Paragraph.php).

Instead of fixing this node-specific or block_content specific, let's assume paragraphs can also exist on other entity types (they can) and work with interfaces.
PS: I think MR!1 in 🐛 Errors on search-only for deep-nested paragraphs Needs review is the better long-term solution!
