Powershell core to powershell - powershell

Question

I'm running an Ubuntu EC2 instance with Pwsh installed to remote execute AD commands on one of our servers. 2sd hop is set-up correctly and i'm able to run AD commands but when executing my script i get the following error (Scripts works fine directly on the 2sd hop machine):
The search filter cannot be recognized
+ CategoryInfo : NotSpecified: (:) [Get-ADUser], ADException + FullyQualifiedErrorId : ActiveDirectoryServer:8254,Microsoft.ActiveDirectory.Management.Commands.GetADUser
+ PSComputerName : corpmaint02
#!/usr/bin/pwsh
$employeeEmail = 'myemail#contoso.com'
$session = New-PSSession -ComputerName corpmaint02 -ConfigurationName corpmaint02 -Credential contoso\myadminaccount
Invoke-Command -Session $session -ArgumentList $employeeEmail -ScriptBlock{
Get-ADUser -Filter "EmailAddress -eq '$employeeEmail'" -Properties EmailAddress | Disable-ADAccount
Write-Host $employeeEmail has been 'disabled.'
}
Remove-PSSession -ID $session.ID
[GC]::Collect()
Any help would be appreciated.
Update: new code:
#!/usr/bin/pwsh
$cred=Get-Credential domain\myadmin
$employeeEmail = 'myemail#contoso.com'
Invoke-Command -ComputerName corpmaint02 -Credential $cred -ConfigurationName corpmaint02 -Authentication Negotiate -ArgumentList $employeeEmail -$
Get-ADUser -Filter "EmailAddress -eq '$($Args[0])'" -Properties EmailAddress | Disable-ADAccount -verbose
Write-Host $employeeEmail has been 'disabled.'
}
I modified my code as follow and it works expect for the lack of permissions to disable the account which odd because my admin account has rights to do so.
Insufficient access rights to perform the operation

New code to elevate:
#!/usr/bin/pwsh
$cred=Get-Credential domain\myadmin
$employeeEmail = 'user1#contoso.com'
Invoke-Command -ComputerName corpmaint02 -Credential $cred -ConfigurationName corpmaint02 -Authentication Negotiate -ArgumentList $employeeEmail,$cred -ScriptBlock{
$currentUser = New-Object Security.Principal.WindowsPrincipal $([Security.Principal.WindowsIdentity]::GetCurrent())
$testadmin = $currentUser.IsInRole([Security.Principal.WindowsBuiltinRole]::Administrator)
if ($testadmin -eq $false) {
Start-Process powershell.exe -Verb RunAs -ArgumentList ('-noprofile -noexit -file "{0}" -elevated' -f ($myinvocation.MyCommand.Definition))
exit $LASTEXITCODE
}
Get-ADUser -Filter "EmailAddress -eq '$($Args[0])'" -Properties EmailAddress | Disable-ADAccount -verbose -Credential $Args[1]
}
Write-Host $employeeEmail 'has been disabled.'

Invoke-Command isn't running with elevated rights, so you can retrieve data but not make changes.
https://ss64.com/ps/syntax-elevate.html
If you use Invoke-Command to run a script or command on a remote computer, then it will not run elevated even if the local session is. This is because any prompt for elevation will happen on the remote machine in a non-interactive session and so will fail.
You can try self elevating in the Invoke-Command scriptblock (from the link above)
If (-NOT ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator))
{
# Relaunch as an elevated process:
Start-Process powershell.exe "-File",('"{0}"' -f $MyInvocation.MyCommand.Path) -Verb RunAs
exit
}
# Now running elevated so launch the script:
& "d:\long path name\script name.ps1" "Long Argument 1" "Long Argument 2"
