passing array of strings parameter to a script flattens it

    I have a script1 that has an array of strings as one of the parameters:

    When script1 is called and I supply it 2 (or more) strings, it works fine, but we call script1 from another script2.

    In this script 2, it's defined/called like this:
    [string[]]$RDSL = @("server1","server2")
    Execute-Script -Command 'powershell.exe -NonInteractive -NoProfile -File "\\unc_path\Script1.ps1" -RDSL $RDSL
    When executed like this, the script gets executed, but it parses the array as simple string (it seems) 'server1 server2' and the command that expects the array fails.

    Any idea what am I doing wrong?

    What is Execute-Script? What kind of script is this script2? Is this script2 able to "enumerate" Powershell arrays?

    Sorry, missed the reply.
    These are scripts that automate server deployment and configuration. There's one master script that has parameters that are parsed to individual scripts using the Execute-Script function that executes scripts and checks exit values (defined in the individual scripts).

    Function Execute-Script {
        $global:LASTEXITCODE = 10000
        #execute the command
        Write-Host -ForegroundColor Cyan "Running '$Command'"
        Invoke-Expression $Command
        if ($LASTEXITCODE -eq 0) {
            Write-Host -ForegroundColor Green "Command '$Command' SUCCESS"
            Write-Log -Message "Command '$Command' finished successfully" -Log $LogFile -Level INFO
        } else {
            write-host -ForegroundColor Red "Command '$Command' FAILED, check log"
            Write-Log -Message "Command '$Command' failed, exit code: $LASTEXITCODE" -Log $LogFile -Level ERROR

    master script (excerpt):

    [string[]]$RDSL = @("server1","server2"),
    Execute-Script -Command 'powershell.exe -NonInteractive -NoProfile -File "\\fs\Scripts\script2.ps1" -ComputerName $ComputerName -RDSL $RDSL -RDGW $RDGW -RDCert $RDCert -RDCertPwd $RDCertPwd'

    script2 (excerpt):

    Set-RDLicenseConfiguration -ConnectionBroker $ComputerFQDN -LicenseServer $RDSL -Mode PerUser -Force
    #the above cmd then fails with the problem I described - from logging it seems it's flattened to string 'server1 server2'

    Is it more clear now?
