I followed How to create a custom entity in Drupal 8 to create a module. When I installed it, I got the following error.
Drupal\Component\Plugin\Exception\PluginNotFoundException: The "dictionary_term" entity type does not exist. in Drupal\Core\Entity\EntityTypeManager->getDefinition() (line 150 of /var/www/html/core/lib/Drupal/Core/Entity/EntityTypeManager.php).
What do I need to change in the following code?
dictionary/Entity/Term.php
