I am having the same problem. My code returns the embed as expected in the classic editor and a front end site editor, but fails in the Gutenberg block editor. For some reason beyond my skill level the WP_Embed class is returning false

The code I am testing is:

	function embed_extras_register_h5p(){

		$regex_url = '#https://h5pstudio\.ecampusontario\.ca/content/([0-9]+)#i';

		wp_embed_register_handler(
				'h5p',
				$regex_url,
				'embed_extras_handler_h5p'
		);
	}

	function embed_extras_handler_h5p( $matches, $attr, $url, $rawattr ) {

		$embed = sprintf(
			'<div class="h5p-embed"><iframe src="https://h5pstudio.ecampusontario.ca/h5p/%1$s/embed" width="894" height="314" frameborder="0" allowfullscreen="allowfullscreen"></iframe></div>',
			esc_attr($matches[1])
		);

		return $embed;
	}

Just experienced this on site where Chaplin used as parent theme. The Theme interface reported it broken with fatal error, with options at bottom to delete or resume (?) Neither did a thing. Manually deleting the theme via ftp and uploading a copy of 2.1.3 fixed it.

You really do not want to be editing the Chaplin theme, your changes will be lost when it is updated. This is the reason to do mods as a child theme.

I’m doing this for a project where I have one custom post type and three custom taxonomies. It takes some code lifting to do! I am not sure I can get everything in. If you look in functions.php you will find the meta data constructor function chaplin_get_post_meta. It looks like he has hooks in where you could add in a child theme functions.php functions to add post_meta data:

// Allow output of additional meta items to be added by child themes and plugins
do_action( 'chaplin_start_of_post_meta_list', $post_meta, $post_id );

I ended up copying the entire chaplin_get_post_meta function to my functions.php and changed it to be toolkit_get_post_meta, and from there I added my own extra code for doing my metadata, e,g,

// Module Taxonomy
if ( in_array( 'module', $post_meta ) && has_term( '', 'module', $post_id ) ) : 
	$has_meta = true;
	?>
	<li class="post-jetpack-portfolio-type meta-wrapper">
		<span class="meta-icon">
			<span class="screen-reader-text"><?php esc_html_e( 'Modules', 'chaplin' ); ?></span>
			<?php chaplin_the_theme_svg( 'bookmark' ); ?>
		</span>
		<span class="meta-text">
			<?php the_terms( $post_id, 'module', __( 'Module: ', 'chaplin' ) . ' ', ', ' ); ?>
		</span>
	</li>
	<?php
endif;

This means in my templates that I made a copy of content.php changed to content-tool.php for my CPT, and call me own metadata function from there

toolkit_the_post_meta( $post->ID, 'single-top' );

It took even more legwork to get the archives working… You might go with JetPack since there is built in support for that, but I loathe the JetPack stuff.
