Magento 2遇到错误的“请求的数量超过购物车中允许的最大数量”。

代码示例：

class CustomAddToCart {
  public function __construct(
    \Magento\Checkout\Model\Cart $cart
  ) {
    $this->cart = $cart;
  }
  public function execute()
  {
    $product = ....
    $this->cart->addProduct($product, ['product' => $product->getId(), 'qty' => 1]);
    $this->cart->save();
  }
}

当购物车进行保存Magento尝试将当前在购物车中的最后一个项目的数量更改为2。由于我们网站中的所有产品仅具有1个库存数量1，只能在购物车中添加一次。所以我不知道为什么Magento这样做。如果有人已经经历过，任何人都可以帮我吗？

xdebug break Point，其中cart中的最后一项从1增加到2

xdebug呼叫堆栈跟踪

原文

code example:

class CustomAddToCart {
  public function __construct(
    \Magento\Checkout\Model\Cart $cart
  ) {
    $this->cart = $cart;
  }
  public function execute()
  {
    $product = ....
    $this->cart->addProduct($product, ['product' => $product->getId(), 'qty' => 1]);
    $this->cart->save();
  }
}

When the cart do the save Magento tries to change the quantity of the last item currently in the cart into 2. Since all products in our website only have a stock quantity of 1 it can only be added in the cart once. So I do not know why Magento is doing this. Can anybody please help me if someone already had experience this.

xdebug break point where last item in cart is increased from 1 to 2

xdebug call stack trace of the trace
