Powershell Revoke CA

Hello

I have a Powershell which revokes the User and Computer CA but gives Error:

Revoking "05" -- Reason: Unspecified
ICertAdmin::RevokeCertificate: The parameter is incorrect. 0x80070057 (WIN32: 87 ERROR_INVALID_PARAMETER)
CertUtil: -revoke command FAILED: 0x80070057 (WIN32: 87 ERROR_INVALID_PARAMETER)
CertUtil: The parameter is incorrect.

Where is the problem?

Import-Module PSPKI
Import-Module ActiveDirectory
$RequesterNameComputer = "A\B$";
$RequesterNameUser = "A\C";

certutil -view -out "RequestID,SerialNumber,RequesterName,RequestType,NotAfter,CommonName,Certificate Template" csv > "$env:TEMP\tempcerts.csv";

$Csv = Import-Csv -Path "$env:TEMP\tempcerts.csv";
$csv | Select-Object "requester name" | Group-Object -Property "requester name" | Sort-Object -Property count;

$computer = $csv | Where-Object {$_."requester name" -eq $RequesterNameComputer} | ?{$_."Certificate Template" -like "*PlaygroundComputer"};
$computer

ForEach ($com in $computer){
certutil -revoke $com.SerialNumber 5
$computer
}
$User = $csv | Where-Object {$_."requester name" -eq $RequesterNameUser} | ?{$_."Certificate Template" -like "*User"};
$User

ForEach ($usr in $User){
certutil -revoke $usr."SerialNumber" 5
}
$User
