Azure 策略错误：CaseSensitiveDeploymentParameterNamesFound

Question

我有以下策略定义来为我的订阅资源组中的所有 Linux 虚拟机运行脚本。 我有4个Linux虚拟机，OpenSuse，Ubuntu18.04，Ubuntu-server22.04，OracleLinux8.6。 我部分复制了 Microsoft 在 Linux 台虚拟机上部署脚本的操作，并进行了修改以安装名为 bac.sh 的脚本。 为了进行测试，我在 Linux VM 上安装了脚本并且它可以运行。 我确保它不会提示用户输入任何值，除了脚本需要在 Linux VM 上作为“sudo bash bac.sh”运行。 Microsoft 使用以下命令：“commandToExecute”：“bash rac.sh”； 在 Linux 台虚拟机上运行脚本

在Remediation任务中查看“部署错误”后，发现如下错误信息

代码 CaseSensitiveDeploymentParameterNamesFound 消息部署参数使用区分大小写的名称。 错误参数名称：vmName。 有关使用详情，请参阅https://aka.ms/arm-keyvault 。

任何评论/帮助将不胜感激！

我认为 Azure 资源管理器实际上遇到了删除重复的vmName/vmname属性的问题，因为原始错误中存在区分大小写的问题。 我最想尝试的事情是确保您将策略 JSON 作为文件备份在您的计算机上。 删除重复的 vmname 条目并保存文件。 然后删除Azure中原来的Policy，从编辑好的本地文件重新创建。
