Jetpack – Gutenberg Gallery Images Do Not Open on Click/Zoom in jp-carousel

Overview of the Issue

If you create a Gutenberg Gallery with the Jetpack plugin, you will see this error on the translation:

Warning: Invalid argument supplied for foreach() in …/wp-content/plugins/jetpack/modules/carousel/jetpack-carousel.php on line 738

This issue is fixed. Updating to the latest version solves it on your site, so you only need this workaround if you can’t update yet.

Make a full backup of your site.
Open the wp-content/plugins/jetpack/modules/carousel/jetpack-carousel.php file.
Look for line 786.

Change:

$attachment_id = absint( $class_id[2] );

With

$attachment_id = apply_filters( 'wpml_object_id', absint( $class_id[2] ), 'attachment' );
