Error:
PHP-ERROR.WARNING: Trying to access array offset on value of type bool
{"file":"/usr/local/wordpress/wp-content/plugins/meta-box/inc/fields/image.php","line":145}
{"wp":{"doing_cron":false,"doing_ajax":false,"is_admin":false,"doing_rest":true,"user_id":XX}}
This is due to RWMB_Image_Field::file_info calling wp_get_attachment_image_src and assuming it's an array always. This function can return false, and is a silent error in PHP < 8.x.
A simple addition like so should resolve the issue:
$image = wp_get_attachment_image_src( $file, $args['size'] );
if ( ! $image ) {
return false;
}
.
