【中文标题】Terraform 上的 Azure 应用服务自动缩放错误【英文标题】：Azure App Service autoscale Error on Terraform 【发布时间】：2021-10-30 22:58:26 【问题描述】：尝试使用 terraform for azure app service plan 创建自动缩放配置 但低于错误，
指标名称已验证，看起来不错，但不确定此错误，因为 terraform 计划中没有提供太多详细信息

【问题讨论】：
【参考方案1】：它发生在最初在门户中创建自动缩放计划时，
因此，您可以尝试在应用计划设置 > 横向扩展下的门户中删除 JSON Autoscale setting name，然后重试 terraform 应用。
