ps_shopping cart mode ajax error out of stock

[Ludo62200]

Hi,

I have a site with prestashop 1.7. Adding to the basket is done in ajax mode and when I add a product more than the stock, I get an empty popin. In the "Network" tab of the inspector, I have a call to / cart which gives me an error "the item in your basket is no longer available in this quantity ..."

After there are a call to /modules/ps_shoppingcart/ajax

 

Can you help me find a solution to my issue ?

 

Thanks
