Azure 资源管理器模板 - 属性循环不工作不断收到错误，因为不需要复制索引

Question

我正在尝试根据负载均衡器的可用文档 https://docs.microsoft.com/en-us/azure/azure-resource-manager/templates/copy-properties 使用属性复制循环部署 Arm 模板，但它无法正常工作。模板验证失败错误为“无法评估语言表达式属性 'protocol'。

如果我删除负载均衡器规则副本并尝试单独迭代健康探测器属性它的工作。

我们已经尝试了相同的代码，能够重现上述问题并找出根本原因。

错误详情：-

在您复制的模板中 loadBalancingRules 您正在使用以下内容:

"protocol": "[parameters('lbprobe')[copyIndex('loadBalancingRules').protocol]]",
                            "frontendport": "[parameters('lbprobe')[copyIndex('loadBalancingRules').frontendPort]]",
                            "backendport": "[parameters('lbprobe')[copyIndex('loadBalancingRules').backendPort]]",

您应该使用以下内容：

"protocol": "[parameters('lbprobe')[copyIndex('loadBalancingRules')].protocol]",
"frontendport": "[parameters('lbprobe')[copyIndex('loadBalancingRules')].frontendPort]",
"backendport": "[parameters('lbprobe')[copyIndex('loadBalancingRules')].backendPort]",
