在同一个功能应用程序中发布另一个功能后，Azure功能失败，但再次发布时效果很好

Question

我在功能应用程序中有一个天蓝色的功能Function1。在运行时执行得很好。

我在同一个功能应用程序中有另一个天蓝色功能Function2。

每当我发布Function2时，Function1都会开始失败，并显示以下错误消息：

我们在上面的错误消息中看到，它只有

的日志

[Info] Function started (Id=57101022-3a64-4a00-b67a-ff7628f0e2a8)

和

[Error] Function completed (Failure, Id=57101022-3a64-4a00-b67a-ff7628f0e2a8, Duration=519ms)

并且执行甚至不在函数内部。

我有解决此问题的方法。那就是重新发布Function1，错误消失并且Functions执行正常。

如何避免每次发布Function2时都需要重新发布Function1来避免上述错误？

谢谢

值得说明的是，对于功能而言，部署单位是整个应用程序。您不仅要发布或更新单个功能，还要发布整个应用程序。

就可能引起问题的原因而言，我并不满意。看的地方之一就是您的发布方式。去年，我们引入了run from package，使您可以发布单个zip工件。如果您未启用此选项，则有可能在function1仍在尝试执行时复制了一些文件，并且它们最终处于错误状态。如果是这种情况，启用从程序包运行应该可以解决您的问题（应该是Visual Studio发布中的复选框，或者是VS Code中的默认选项）。
