Error when having pages with categories

I have the following code in my functions.php to enable setting categories for pages:

`
add_action(‘init’, function () {
register_taxonomy_for_object_type(‘category’, ‘page’);
});
add_action(‘pre_get_posts’, function ($wp_query) {
if ($wp_query->get(‘category_name’)) $wp_query->set(‘post_type’, ‘any’);
});
`

The line if ($wp_query->get('category_name')) $wp_query->set('post_type', 'any'); will result in an error in combination with this plugin.
