Webservice bug ? Cart's lines are deleted when updating date of availability.

[BatGo]

Hi,

Prestashop 1.7.5.2.

1. Add a product to your cart.
2. Then use the webservice "combinations" to update the field "available_date".
3. The cart's lines are deleted.

Normal ?? If you update this date from the backoffice of your declination, there's no deleting.

 I've compared the diffrences exporting all by database between the 2 methods, and the differences are just the lines of my table ps_cart_product.

The tables ps_product_attribute and ps_product_attribute_shop are correctly updated.

 

So I'll update the database and not use the webservice method, but it's not a good way.

Any information about that ? Is it a bug ?

 

Thanks.
