Arm template dependsOn函数对嵌套模板的工作方式是否不同

          }
        }
      }
    ],

我试过以下几种组合，但都失败了

                        "[resourceId(subscription().subscriptionId, variables('ResourceGroupName'), 'Microsoft.Storage/storageAccounts', variables('storageAccountName'))]",
                        "[resourceId(variables('ResourceGroupName'), 'Microsoft.Storage/storageAccounts', variables('storageAccountName'))]",
                        "[resourceId('Microsoft.Storage/storageAccounts', variables('storageAccountName'))]"

我可以在部署模板中不使用resourceId的变量吗？是否有任何限制或技巧我应该担心？它必须是纯文本，而不是params或vars吗
