【问题描述】：
我有一个 Laravel 5.4 应用程序。
我的问题是我每周有一份工作要排队处理一些电子邮件。
像这样：
Mail::to($user)->queue(new \App\Mail\INBND10\i01($user));
一切看起来都很好，一些电子邮件已送达，但在发送了几封电子邮件后，我得到了一个尝试获取非对象属性异常。
Sentry 告诉我这是在 Mail 构建方法中，如下所示：
有什么想法会导致这种奇怪的行为吗？

【问题讨论】：
-
你能粘贴错误的堆栈跟踪吗？
-
如果您尝试访问父对象的可选属性，通常会发生这种情况，例如
$user->image->id;如果$user->image是null，并且您在尝试访问->id之前没有检查，您将遇到该错误。这只是一个例子；寻找链接的->访问权限，尤其是在view中，并确认您的逻辑。 -
@Paras 我已经用堆栈跟踪更新了 OP
