PHP 8.x warning: pass-by-reference parameter in block-migrate/loader.php closure

[austinginder]

Description

The the_post callback in includes/block-migrate/loader.php:29 declares its parameter as pass-by-reference:

function( WP_Post &$post ) {

WordPress's WP_Hook::apply_filters() passes arguments by value, so this generates a warning on every page load under PHP 8.x:

PHP Warning: CoBlocks::{closure}(): Argument #1 ($post) must be passed by reference, value given in wp-includes/class-wp-hook.php on line 343

Steps to Reproduce

1. Activate CoBlocks on PHP 8.x
2. Visit any post/page on the frontend
3. Check the error log

Fix

Remove the & from the closure parameter. Since WP_Post is an object, it's already passed by handle — the reference is unnecessary.

- function( WP_Post &$post ) {
+ function( WP_Post $post ) {

Environment

• CoBlocks 3.1.17
• PHP 8.3
• WordPress 6.7
