为什么我收到此错误？ ：Darryldecode \ Cart \ Exceptions \ InvalidItemException validate.required

问题描述

在我的电子商务网站上，我安装了darryldecode / laravelshoppingcart来添加购物车功能。

当我使用“添加到购物车”从产品页面将商品添加到购物车时，出现此错误：-Darryldecode \ Cart \ Exceptions \ InvalidItemException validate.required

这是我的第一个项目，请指导我如何解决此问题。这个项目使我丧命。我可以在这个社区的帮助下完成这个项目。非常感谢。
