I am trying to automate a task to login and verify or not login is success in a nutshell I am able to create.

$username = "XXXX"
$password = "XXXXXXXX"
$ie = New-Object -com InternetExplorer.Application
$ie.visible=$true
$ie.navigate("https://com/login")
while($ie.ReadyState -ne 4) {start-sleep -m 100}
$ie.document.getElementById("user_email").value= "$username"
$ie.document.getElementById("user_password").value = "$password"
$ie.document.getElementById("Loginform").submit()
start-sleep 20
$ie.Document.body

Its throwing error
