AssertionError: "interactive" must be defined in MODULE_NAME.field_type_categories.yml

Problem/Motivation

Problem:

When navigating to the "Add field" UI page (/admin/structure/types/manage/{bundle}/fields/add-field), the site throws a fatal AssertionError and shows a white screen:

AssertionError: "interactive" must be defined in MODULE_NAME.field_type_categories.yml
in Drupal\Core\Field\FieldTypePluginManager->getGroupedDefinitions()

Root cause:

The EmojiReactionItem field type plugin declares category = "interactive" in its @FieldType annotation (EmojiReactionItem.php line 31), but the module ships no emoji_reactions.field_type_categories.yml file to register that category with Drupal's FieldTypeCategoryManager.

Since Drupal 10.1, every category referenced by a field type must be declared in a MODULE_NAME.field_type_categories.yml file. Without it, FieldTypePluginManager::getGroupedDefinitions() (line 183) asserts FALSE and crashes.

Fix:

Add the file emoji_reactions.field_type_categories.yml to the module root:

interactive:
  label: 'Interactive'
  description: 'Fields that provide interactive user engagement features.'
  weight: 10

Steps to reproduce

1. Install the emoji_reactions module.
2. Go to any content type → Manage fields → Add field.
3. The page crashes with the AssertionError above.
