GUID column issues.

I an using the guid cloumn to store a uuid. I also added a uuid column to the post table as a backup if there was ever a problem. After a recent update WP is prepending my UUID value with “https://”.

For example “2C3467A6-2765-478F-81C9-8013F1D623B9” becomes “https://2C3467A6-2765-478F-81C9-8013F1D623B9”

This is causing some problems and I need to fix it. Below is the function I am using to do this.

function wpufe_update_uuid( $post_id ) {

	$uuid = get_post_meta( $post_id, '_uuid', true );
	global $wpdb;
	$wpdb->query( $wpdb->prepare( "UPDATE $wpdb->posts SET guid = %s WHERE ID = %d", $uuid, $post_id ) );
	$wpdb->query( $wpdb->prepare( "UPDATE $wpdb->posts SET uuid = %s WHERE ID = %d", $uuid, $post_id ) );	

	}

add_action( 'wpuf_add_post_after_insert', 'wpufe_update_uuid' );
add_action( 'wpuf_edit_post_after_update', 'wpufe_update_uuid' );
