Azure CD问题：无法获取应用程序服务“ myAppServiceName”发布凭据

Question

我正在尝试在Azure Web应用程序上部署我的发行版。它不起作用，我不知道该怎么办。也许我的应用程序服务或发布管道中的配置中缺少某些内容。我遇到以下错误

Failed to fetch App Service 'myAppServiceName' publishing credentials. Error: Could not fetch access token for Managed Service Principal.

这是我的调试块：

和一些截图

azure missing configuration ?

release pipeline config 1

release pipeline config 2

release pipeline config 3

如果您需要更多信息，请告诉我。.我是新来的，所以可能会错过一些简单的东西...最好的问候

Answer 1

您是否将身份状态设置为“开”？ 像下面

Answer 2

我的研究表明这是一个间歇性问题。 我重新部署了2次，但效果很好。 第一次重新部署-似乎需要等待很长时间才能连接到可用的代理，因此我也取消了该部署，然后重新部署-该方法没有任何问题。

Answer 3

如果这仍然是一个问题，或者某个人遇到了这个问题，那么我所做的就是重新运行该发行版，并且一切顺利。希望有人通过重新发布节省了时间，如果这样做不起作用，则可以尝试其他方法。
