I am trying to copy some files from remote servers to local with the following:

function getfiles {

& C:\Users\myuser\Desktop\stores\getfiles.ps1
  }

function create {
New-Item -ItemType directory -Force -Path C:\Users\myuser\Desktop\stores
}
#####copy files to local#####

$computer = Get-Content C:\Users\myuser\Desktop\stores\computers.txt
$computer | ForEach-Object {
$session=new-pssession -computername $_ -credential (Import-Clixml "mycredentials.xml")
Invoke-Command -Session $session -ScriptBlock ${function:create}
Copy-Item -path "C:\Users\myuser\Desktop\stores\getfiles.ps1" -destination "C:\Users\myuser\Desktop\stores\getfiles.ps1" -recurse -ToSession $session 
Invoke-Command -Session $session -ScriptBlock ${function:getfiles}
Copy-Item -path "C:\Users\myuser\Desktop\stores\UK*" -Destination "C:\Users\myuser\Desktop\stores" -recurse -FromSession $session
Get-PSSession -ComputerName $_ -Credential (Import-Clixml "mycredentials.xml") | Disconnect-PSSession | Remove-PSSession
}

For some strange reason the

Copy-Item -path "C:\Users\myuser\Desktop\stores\UK*" -Destination "C:\Users\myuser\Desktop\stores" -recurse -FromSession $session

Stopped working with the following error:

Copy-Item : A parameter cannot be found that matches parameter name 'FromSession'.
At line:20 char:122
  ... "C:\Users\myuser\Desktop\stores" -recurse -FromSession $sessio ...
                                                       ~~~~~~~~~~~~
      CategoryInfo          : InvalidArgument: (:) [Copy-Item], ParameterBindingException

Some notes:

1. The drives on both servers exist, not the bug mentioned in couple of topics.
2. The getfiles.ps1 executes as expected and it is for file creation.

CodePudding user response：

As mentioned in the comments, this is a long-standing bug that was recently fixed.

Basically, whenever the -Path argument contains wildcard expressions (eg. *) that fail to resolve to any local file system items, the runtime will skip generation of dynamic parameters for the target provider (in this case the FileSystem provider).

-ToSession and -FromSession happens to be dynamic provider parameters.

As you've already found, moving the wildcard to the -Filter parameter works:

Copy-Item -Path "C:\Users\myuser\Desktop\stores" -Filter 'UK*' -Destination "C:\Users\myuser\Desktop\stores" -Recurse -FromSession $session
