php - php 错误消息：可捕获的致命错误：传递给 EIC\EdiBundle\Service\SerialService::validateOrder() 的参数 1 必须是实例

Question

首先让我先说我不是 php 程序员，所以我可能不会理解 php 术语。

话虽如此，我正在尝试通过导入订单来解决此错误，但可以看到它在第 243 行和第 69 行出现错误，但正如我所说的，我不完全确定 SerialService::validation 必须是 salesOrderHeader 的实例意味着什么。我相信给出了一个空值，因为没有像数据库图像中那样创建 JSON 文件，我不知道为什么。 在此处输入图像描述

LineNo：243 消息：可捕获的致命错误：传递给 EIC\EdiBundle\Service\SerialService::validateOrder() 的参数 1 必须是 EIC\SalesBundle\Entity\SalesOrderHeader 的实例，给定 null，在 /var/www/eic/ 中调用src/EIC/EdiBundle/Service/SerialService.php 在第 69 行并定义

代码期望$order变量是EIC\SalesBundle\Entity\SalesOrderHeader类的对象和实例。

在这里，您有todo评论说此函数可以返回null所需的对象。“ToDo”表示代码必须稍后完成 如果为null，则$order = $this->serializeDocumentToEic($document);// ToDo if $order is not SalesOrderHeader Class email and continue 不应调用函数在调用函数之前在代码中添加验证validateOrder $order$valid = $this->validateOrder($order); //line 70

if ($order === null || (is_object($order) && !instanceof EIC\SalesBundle\Entity\SalesOrderHeader) ( {
    // send email as TODO says and 
    continue;
}
