Which hook can be used when updating a product attribut/combination in the products-v2 page ?

[lucasvavon]

I'm developing a module to create specific product prices.

I want to make a specific price update when the purchase price of a product attribute changes with this code :

public function hookXXXXXXXXXXX($params) 
{

    $productAttributeId = (int) $params['id_product_attribute']; // OR $params['object']->id

    // Some code here with  logic to calculate new price 

    Db::getInstance()->update('specific_price', [
        'price' => (float) $newPrice, 
        'from' => date('Y-m-d H:i:s')
    ], 'id_product_attribute = ' . $productAttributeId);
}

I'm looking for a hook that is compatible with the product-v1 page and the product-v2 page.
I've tested different hooks and each one causes different problems:

1. actionProductAttributeUpdate : This hook only works for the productv1 page, it is not triggered in the productv2 page.

2. actionObjectCombinationUpdateAfter : It is triggered in the productv2 page but the behavior is broken. If I update a product attribute (combination), the change operates in the target table. However, if I update a second product attribute, it will have a new specific price, but the first will have a specific price corresponding to the purchase price of the global product.

I hope my explanations are clear.
Thanks in advance !
