问题描述
我已经使用了几个月的功能(即使遇到一些问题也可以看到)，当我开始将使用范围从测试扩展到生产"时，我开始遇到问题.
I've got a function which I've been playing with for a couple of months (even having some issue as can be seen here) and I've started running into issues when I start to scale up the usage from tests to "production".
该函数接受2个值，在Azure表中查找匹配的值，找到后将其删除，然后将新值加在一起.这在测试中效果很好.一旦从每秒几个电话扩展到每秒20-30个电话，它就会因上述响应而失败.
The function takes in a 2 values, looks for a matching value in an Azure Table, removes it if it finds it, then adds the new values in together. This works fine in testing. As soon as I scale up, from a few calls every second, to 20-30 calls a second, it fails with the response mentioned above.
当我深入使用Insights时，实际的问题是抛出了System.InvalidOperationException异常.这是调用堆栈:
The actual issue, when I dive in using Insights, is that a System.InvalidOperationException exception is thrown. Here's the call stack:
System.InvalidOperationException:

带有它的消息是:
Repository has more than 10 non-decryptable secrets backups (host).
很不幸，我不知道那是什么意思.任何对此结果的搜索都只会在几个线程中讨论重新生成密钥，但是同样，我真的不知道这意味着什么.一些线程提到要移回功能的V1，但是我已经在V1上了，所以这是没有选择的.
I unfortunately have no idea what that means. Any searches for this result in just a few threads which talk about regenerating the keys, but again, I don't really know what that means. Some threads mention moving back to V1 of the functions, but I'm already on V1, so that's no an option.
此功能是怎么回事，我该如何解决?
What is going on with this function and how do I fix it?
对于任何正在查看此内容的Azure员工，我的功能ID为:
For any Azure employees looking at this, my function ID is:
2019-01-18T15:52:18.658 [Info] Function started (Id=fc6850e8-7554-46d8-81ec-4d1697c7b572)
推荐答案
删除D:\home\data\Functions\secrets解决了该问题.
总体而言，我了解到，无论您从Azure Function中获得什么奇怪的行为，Kudu始终是您进行调查的最佳工具.
In general I learned that whatever strange behavior you get from Azure Function, Kudu is always your best tool for investigation.
这篇关于调用"Azure函数"调用失败，并显示“函数主机未运行".的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
