使用 CSOM Powershell 关联批准工作流

Question

我正在尝试将审批工作流附加到我的 SharePoint 库，但每次我都收到 'value cannot be null',

但我没有找到哪里出错了，

下面是我正在尝试的 PowerShell 代码

是否缺少任何参数来提供值？

其他功能只是检查列表是否存在，如果不存在则创建它，同样在创建列表时，我无法在方法 createListByTemplate()

中找到列表模板 f0r Task (2010)

谢谢帕鲁

我分享的以上代码绝对可以正常工作，仅此而已您需要启用以下功能才能使用 SharePoint 2010 审批工作流。

使用 CSOM Powershell 关联批准工作流
