Tôi gặp lỗi này trên một số sản phẩm có sản phẩm liên quan:
Warning: Invalid argument supplied for foreach() in vendor/magento/module-catalog/Block/Product/ProductList/Related.php on line 129
Vấn đề này chỉ xảy ra khi bộ đệm toàn bộ trang được bật. Thật không may, vô hiệu hóa nó không phải là một tùy chọn vì sự khác biệt về tốc độ là rất lớn (nhanh hơn 2 giây với bộ đệm trang).
Tôi đã thử mọi thứ mà tôi biết: xóa chủ đề của chúng tôi, các mô-đun tùy chỉnh, v.v.
Môi trường: sản xuất, 2.1.0, véc ni.
Đây là dấu vết ngăn xếp đầy đủ:

Ý tưởng đâu ra mà tìm?
Tại dòng 129 in vendor/magento/module-catalog/Block/Product/ProductList/Related.php
$this->getItems()
là null:
/**
* Return identifiers for produced content
*
* @return array
*/
public function getIdentities()
{
$identities = [];
var_dump($this->getItems());
foreach ($this->getItems() as $item) {
$identities = array_merge($identities, $item->getIdentities());
}
return $identities;
}
Cảm ơn!
