positional-parameter - 键在指定状态下无效 - 找不到接受参数“+”的位置参数

Question

我试图了解此错误的实际含义。我是 PowerShell 的新手，无法弄清楚这一点。我搜索了类似的问题，但内容与我的要求不同。

简而言之，该脚本正在查询数据历史系统以获取批次/批号和该批次的开始时间。该脚本将使用任务调度程序每分钟运行一次。这尚未设置，因为我仍处于测试阶段。我已经设置了一个服务帐户，以便脚本运行。其详细信息存储在 cred 文件中。该脚本使用此批次/批号创建一个文件夹。该脚本会创建一个包含批次编号以及批次开始日期和时间的日志文件。然后，当文件从工厂上传到源文件夹时，脚本会搜索服务器上的源文件夹，脚本会将文件移动到已创建的具有正确批号的文件夹中。如果文件在批处理开始和结束时间之外，则文件将被移动到非批处理文件夹中，将在其中手动查看它们。

我已经完成了测试，我手动将文件添加到服务器上的源文件夹并且一切正常，并且没有得到“找不到从脚本接受参数“+”的位置参数。

我正在研究服务器配置和权限级别，但据我所知，没有任何改变。我看不出脚本有什么问题，但希望有人可以给我一些指示。

下面的错误代码
