Powershell not recognizing boolean argument

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: [email protected]
    [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)
