Что не так с моим скриптом powershell?:(

Question

Я пытаюсь создать автоматический сценарий, который автоматически направляет на защищенный веб-сайт в IE, вводит учетные данные для входа в систему и переходит на вкладку базы данных и ссылку на базу данных для загрузки.Это не потребует взаимодействия с пользователем и будет инициировано через планировщик задач Windows.

Тем не менее, он работает около 75% времени.Я новичок в powershell и совершил ошибки новичка, поэтому любая помощь или направление будут высоко оценены.Спасибо!

 PowerShell.exe -windowstyle hidden {

 function Get-TimeStamp {
 return "[{0:MM/dd/yy} {0:HH:mm:ss}]" -f (Get-Date)
                }
 Write-Output "$(Get-TimeStamp) Script Executed $dc" | Out-file C:\Users
 \JohnSmith\Desktop\Script\ScriptLog.txt -append

 $username = "admin"
 $password = "admin123"

 $ie = new-object -com InternetExplorer.Application

 #Navigate to the login page
 $ie.navigate("Login Page")
 #Wait for the page to finish loading
 do {sleep 1} until (-not ($ie.Busy))
 $ie.visible = $true #comment this line after debugging

 #Assigning DOM to $doc variable
 $doc = $ie.document

 try {
    $usernameField = $doc.getElementById('userName')  
    #write-host $usernameField
    $usernameField.value = $username
    write-host $username

    $passwordField = $doc.getElementById('password')   
    $passwordField.value = $password
    write-host $pass

    #Find and click the submit button
    $submitButton = $doc.getElementById('login')    
    write-host $submitButton
    $submitButton.click()
    #Wait until login is complete
    do {sleep 1} until (-not ($ie.Busy))

    } catch {$null}

$wshell.AppActivate('title of the application window')

Вот мой законченный сценарий.Это не так элегантно, как хотелось бы, но оно делает то, что мне нужно, сейчас!Спасибо!
