Setting PowerShell script entry password

Hi,

I am trying to update my PowerShell script entries (Embedded script) which have their username and password passed as plain text variables in the arguments field. I am trying to move these values to the dedicated username and password fields on the entry, but I am having trouble moving the password.

Import-Module Devolutions.PowerShell
$RDPSessions  = Get-RDMSession | Where-Object {$_.ConnectionType -eq "PowerShell"}
foreach ($s in $RDPSessions)
{
    $words = $s.PowerShell.Arguments -split ' '
    if ($words.Length -eq 4) {
        $username = $words[2]
    } elseif ($words.Length -eq 5) {
        $username = $words[2]
        $password = $words[4]
    } else {
        continue
    }
    if ($password -ne "") {
        $safePassword=ConvertTo-securestring $password -asplaintext -force
        Set-RDMSessionPassword $s.ID -Password $safePassword -Refresh
	    $test =Get-RDMSessionPassword $s.ID -AsPlainText
        $test

    }
    $s.PowerShell.UserName = $username
    Set-RDMSession $s
    $s.Name,$username, $password -join ' - '
}

When the $test variable is printed, the RDMSessionPassword returnes the newly set value. If I try to add another same check after Set-RDMSession it returns an empty value, as if the newly reloaded session does not contain the value anymore. Even after commenting out the Set-RDMSession call, the password is not applied to the entry. It is not visible on the entry and the export also doesn't contain the PowerShell.SafePassword value.

I would try to set the password via the $s.PowerShell.SafePassword variable, but I do not know how to generate the correct Base64 string that is used in the field. Setting the field this way with a known Base64 value from an existing "SafePassword" field does seem to work though.

Kind regards,
