我正在尝试将一些VS测试设置为在Windows服务器计算机上远程运行。它会将所需的工件下载到目标计算机，但在尝试部署测试代理时，它会因以下不明确的错误而失败：
The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: Exception calling ".ctor" with "2" argument(s): "One or more errors occurred."'. For troubleshooting, refer https://aka.ms/remotevstest.
我查看了ps脚本runnning，即TestAgentConfiguration.ps1，看起来它在尝试运行此行时失败
$DtaAgentClient = New-Object Microsoft.VisualStudio.TestService.Utility.TestExecutionServiceRestApiHelper -ArgumentList $TfsCollection, $PersonalAccessToken
但是，我确实可以从目标机器访问TFS服务器......任何想法？
以下是整个日志：
