在 key 保管库访问策略中引用托管标识时，Azure ARM 模板 ResourceNotFound 错误

Question

在启用的逻辑应用上部署具有托管标识访问策略的 KeyVault 服务时，它会失败，因为它尚不存在。我确实为逻辑应用程序添加了依赖项。

奇怪的是这个模板已经工作了几周，现在每次都失败，所以我有点困惑。我从 MS 的快速入门模板中复制了此内容。但这不是问题，因为如果您查看错误，它会指向正确的目标资源。如果我在失败后单击重新部署，此模板也可以工作，因为当时托管身份已经存在。我测试了一下，还是失败了。

这是我的 ARM 模板

我将此作为应用服务的引用:

[reference(resourceId('Microsoft.Web/sites', variables('webAppName')), '2016-08-01', 'Full').identity.principalId]

当然还有dependsOn:

[resourceId('Microsoft.Web/sites', variables('webAppName'))]
