PayPal Module Error

[Bitfarmer]

Running Phenixsuite 1.6.2.31 and Paypal Module V15 I am still seeing an error that I believe is in the module itself. This is the error:

Fatal error: Uncaught Error: Call to undefined method Attribute::getAttributeMinimalQty() in 
 /var/www/sites/site/store/modules/paypal/paypal.php:1620

When I change line 1620 from

$minimal_quantity = Attribute::getAttributeMinimalQty($id_product_attribute);

To this

$minimal_quantity = AttributeProduct::getAttributeMinimalQty($id_product_attribute);

Everything works. Now this bug might have been there a long time (or I'm stupid).
On the other hand it may save someone a lot of trouble. If it does please let me know

No you are not stupid and this bug has been there for 2 years
v16 will be corrected (The Attribute class no longer exists because it is a reserved word since PHP8 and this line had escaped me)

Thanks for your feedback
