Describe the bug
Accessing a registered block pattern that has doesn't have a categories objects crashes the block editor.
According to the existing documentation , a category is not required.
To reproduce
You must first activate a theme that does not have any of its own block patterns shipped with it. (e.g. blankslate is one example)
- Register a block pattern without a category; example below, can be placed in your theme's functions.php or wherever you prefer.
register_block_pattern(
'skorasaurus/test-case-block-pattern',
array(
'title' => __( 'a simple heading', 'what should this be' ),
'description' => _x( 'mmm..cake', ' this is slang and has more nuance in english', ''),
'content' => '<!-- wp:heading -->
<h2>The history of cake</h2>
<!-- /wp:heading -->',
)
);
- add the
remove_theme_support('core-block-patterns');
- create a new post or page in block-editor
- Go to the patterns tab
- "The editor has encountered an unexpected error." appears; and in console, the following:
Uncaught TypeError: t.categories is undefined
