我的队列触发函数显示异常行为。触发后，它会在几分钟后成功完成。
[09.09.2020 15:46:16] Executed 'CalculateStuff' (Succeeded, Id=c56f689a-0a56-4bcf-85ca-080cbbc2b6d0)
此行后大约1分钟，功能应用程序显然引发了错误，因为在终端（在本地运行时）中，由于已达到MaxDequeueCount为1，它显示消息已被移至-poison队列的提示。
[09.09.2020 15:47:03] Message has reached MaxDequeueCount of 1. Moving message to queue 'queue-name-poison'.
我明确选择此值为1（默认值为5），因为该函数内部的一部分将请求上载到外部sftp服务器，然后轮询以进行回复。这可能需要5分钟。如果MaxDequeueCount> 1并且出现错误，则此过程会发生多次，这不是我想要的。
但是令我感到困惑的是，函数本身成功完成了，而结束仍然以某种方式抛出了异常。我不知道这是哪里来的。您有什么想法吗？
非常感谢您的帮助！
