Filter callback not getting called

Hey there,

I am trying to use one of the filters from the documentation.

add_filter('uni_cpo_in_cart_formula_before_formula_eval', 'ks_DEBUG_unicpo', 10, 3);
function ks_DEBUG_unicpo($main_formula, $product_data, $product_id) {
	error_log(sprintf('ks_DEBUG_unicpo'));
}

The documentation suggests that the hook is available in the free version but my callback is not called in the cart page (or the product page). Other cart page filters I have added in the same file for woocommerce work.

Is the hook still available?

Regards
