无法从Terraform创建Azure自动缩放设置服务（StatusCode=409） 描述

您好，我正在尝试为机器缩放集Azure添加基于CPU的自定义自动缩放设置，但出现以下错误：

错误：创建自动缩放设置“缩放测试”（资源组“MyResourceGroup”）时出错：insights.AutoscaleSettingsClient#CreateOrUpdate:发送请求失败：StatusCode=409--原始错误：autorest/azure:服务返回错误。状态=

受影响的资源

• azurerm\u监视器\u自动缩放\u设置

地形版本 尝试以下方法：

• 地形11
• 地形12
• 地形13

地形配置文件 预期行为 为我的机器缩放集Azure服务创建我的自定义自动缩放设置

复制步骤 谁能帮帮我吗
