Audio attribute kills server side rendered block

Below you are adding an attribute client side

function addAttribute( settings ) {

	// check if object exists for old Gutenberg version compatibility
	if (typeof settings.attributes !== 'undefined' && typeof settings.render_callback !== 'undefined') {
		settings.attributes = Object.assign( settings.attributes, {
			beyondwordsAudio:{
				type: 'boolean',
				default: true,
			}
		});
	}

	return settings;
}

addFilter(
    'blocks.registerBlockType',
    'beyondwords/beyondwords-audio-block-attribute',
    addAttribute
)

The attribute was never added server side however. This kills all server side rendered blocks.

“beyondwordsAudio is not a valid property of Object.”

I could not find a public github to make a PR request. I have added the fix to the code here

add_filter( 'register_block_type_args', function( $settings ) {

    if (isset($settings['attributes'])) {
        $settings['attributes']['beyondwordsAudio'] = [
            'type' => 'boolean',
            'default' => true,
        ];
    }

    return $settings;
});
