powershell - 传递托管元数据术语数组时，set-pnplistitem 出错

Question

使用 pnp powershell 修改 sharepoint 在线列表项，我正在尝试更新现有列表项，添加一组托管元数据术语，但是当我尝试使用多个术语更新条目时，该命令一直失败。或者，如果我传递一个带有单个术语的数组变量。

set-pnplistitem -list "Pages" -Identity $itemID -values @{"Category"=("How-To")} -SystemUpdate #WORKS
set-pnplistitem -list "Pages" -Identity $itemID -values @{"Category"=("For Teams That Create Digital Content")} -SystemUpdate #WORKS
set-pnplistitem -list "Pages" -Identity $itemID -values @{"Category"=("How-To","For Teams That Create Digital Content")} -systemUpdate #FAILS
$test=@("How-To")
set-pnplistitem -list "Pages" -Identity $itemID -values @{"Category"=$test} -SystemUpdate # FAILS
$test=@("How-To","For Teams That Create Digital Content")
set-pnplistitem -list "Pages" -Identity $itemID -values @{"Category"=$test} -SystemUpdate # FAILS

error:
set-pnplistitem : Object reference not set to an instance of an object.

我做错了吗，还是 set-pnpListItem 有错误？
