Поиск по post_title и some_acf_field

Как можно реализовать поиск по post_title и some_acf_field?
Код ниже не работает:

$post_args = [
		'post_type' => ['post', 'page', 'custom_project', 'custom_location', 'custom_developer'],
		'numberposts' => -1,
		'meta_query' => [
			'relation' => 'OR',
			[
				'key' => 'post_title',
				'value' => $post_args_value,
				'compare' => 'LIKE',
			],
			[
				'key' => 'some_acf_field',
				'value' => $post_args_value,
				'compare' => 'LIKE',
			],
		 ],
	];

	$all_posts = get_posts($post_args);
