Powershell not recognizing boolean argument - powershell

Question

I have the following PS script
param (
# FQDN or IP address of the Domain Controller
[Parameter(Mandatory=$True)]
[string]$ADaddress,
# Active directory domain name
# example: directory.local
[Parameter(Mandatory=$True)]
[string]$ADDomainName,
# Domain admin
# example: administrator#directory.local
[Parameter(Mandatory=$True)]
[string]$domainAdmin,
# Domain admin password
[Parameter(Mandatory=$True)]
[string]$domainAdminPassword,
# User to be added
# example: testUser
[Parameter (Mandatory=$True)]
[string]$newUsername,
# Password of th user to be added
# example: 1!2#4%6
[Parameter (Mandatory=$True)]
[string]$newPassword,
# SAM account name of the user to added
# example: testuser
[Parameter (Mandatory=$True)]
[string]$newSamAccountName,
# Display name of the user to added
# example: "Test user for test purposes"
[Parameter (Mandatory=$True)]
[string]$newUserDisplayName
)
$domainAdminSecurePassword = $domainAdminPassword | ConvertTo-SecureString -asPlainText -Force
$domainAdminCredential = New-Object System.Management.Automation.PSCredential($domainAdmin, $domainAdminSecurePassword)
$newUserSecurePassword = $newPassword | ConvertTo-SecureString -asPlainText -Force
$UPN= $newUsername+"#"+$ADDomainName
Invoke-Command -ComputerName $ADaddress -Credential $domainAdminCredential `
-ScriptBlock {`
param($newUsername, $newUserSecurePassword, $newSamAccountName, $newUserDisplayName, $UPN) `
new-aduser -name $newUsername -AccountPassword $newUserSecurePassword -Enabled $true -SamAccountName $newSamAccountName -DisplayName $newUserDisplayName -UserPrincipalName $UPN -PasswordNeverExpires $true`
} `
-ArgumentList $newUsername, $newUserSecurePassword, $newSamAccountName, $newUserDisplayName, $UPN
Tho problem I get when invoking this script is:
Cannot convert 'System.String' to the type 'System.Nullable`1[System.Boolean]' required by parameter 'PasswordNeverExpires'.
I tried passing 1 instead, passing [bool]$true but the result remains the same. I am new to PS and I'm lost here. Can anyone shine some light on what the problem may be?

Answer 1

Alright, I found what the problem was.
Changed:
-PasswordNeverExpires $true`
to
-PasswordNeverExpires $true `
(added a space after true)

Answer 2

replacing $true with a variable did it for me.
So this:
$command = 'New-CMApplicationDeployment -Name $Name -CollectionName $Col -OverrideServiceWindow $true -Comment $Com -AvailableDateTime $Adt -DeployAction Install -DeployPurpose Available -UserNotification DisplaySoftwareCenterOnly'
Invoke-Expression -Command "& $command"
became:
$t = $true
$command = 'New-CMApplicationDeployment -Name $Name -CollectionName $Col -OverrideServiceWindow $t -Comment $Com -AvailableDateTime $Adt -DeployAction Install -DeployPurpose Available -UserNotification DisplaySoftwareCenterOnly'
Invoke-Expression -Command "& $command"
Its dumb but it worked.
