Powershell JEA don't work with file operation

Question

Hello!

Try to write a script that will connect to remote computer and perform some tasks.

It use JEA and invoke-command

Example:

Invoke-Command -ComputerName 'ServerName' -ConfigurationName MyJEATask -ScriptBlock {}

Most of commands work fine, except all filesystem commands: test-path, get-childitem, new-item.

When i perform enter-pssession and get-command i could see, that all of them are available.

But when try to perform something with files - get an error.

test-path - always show False

new-item - Cannot find a provider with the name 'FileSystem'.

get-item - Cannot find a provider with the name 'FileSystem'.

get-childitem - Cannot find a provider with the name 'FileSystem'.

Of couse all of them are added to PSRC file without any parameters:

VisibleCmdlets = 'New-Item','Test-Path','Unregister-ScheduledTask','get-date','New-ScheduledTaskAction','New-ScheduledTaskSettingsSet','New-ScheduledTask','Register-ScheduledTask','Get-Childitem','Get-ScheduledTask','New-ScheduledTaskTrigger','out-file','get-item'

What is a problem with this provider ? How could i add it ?

Answer 1

Hello there,

Might be a permission or role issue within the scipt.

When creating a JEA endpoint, you need to define one or more role capabilities that describe what someone can do in a JEA session. A role capability is a PowerShell data file with the . psrc extension that lists all the cmdlets, functions, providers, and external programs that are made available to connecting users.

The reason was, that i have to add FileSystem provider to . psrc file

VisibleProviders = 'FileSystem'
