Comment (by wildworks):

 I could not reproduce it in either WordPress 6.0 or 6.1-RC6. Did it work
 correctly in WordPress 6.0?

 Here is my test procedure:

 - Run `npx @wordpress/create-block test-block` directly under the plugin
 directory
 - Update test-block.php as follows:



 {{{
 function create_block_test_block_block_init() {
         register_block_type(
                 __DIR__ . '/build',
                 array(
                         'render_callback' => function( $attributes,
 $content, $block ) {
                                 return 'rendered';
                         },
                 )
         );
 }
 add_action( 'init', 'create_block_test_block_block_init' );
 }}}



 - Insert the block into the editor and save it
 - Confirm that no errors occur in both the editor and the front end
