Powershell "Cannot process argument"

I am running into below error while trying to run this piece of code, can someone throw some light on what I am missing here? Thanks!

 $SecurePassword = ConvertTo-SecureString "password" -AsPlainText -Force -ErrorAction Stop
 $SSCred = New-Object System.Management.Automation.PSCredential ("PROD\username", $SecurePassword) -ErrorAction Stop
 Write-Host "$(Get-date): Done Secret Server Login"
    
 $AzureProdLock = Get-SecretServerCredential -SamAccountName pjob9001 -OperatorCredentials $SSCred -Verbose:$True -ErrorAction Stop
 $Null = Connect-AzAccount -ServicePrincipal -Credential $AzureProdLock -Tenant "tenantId" -ErrorAction Stop -WarningAction SilentlyContinue

Error msg:
"Exception calling ".ctor" with "2" argument(s): "Cannot process argument because

the value of argument "userName" is not valid. Change the value of the "userName" argument and run the operation again.""

Try single quote "PROD\username" => 'PROD\username'

Hello Saravanaraj,

PowerShell protects access to variables, aliases, functions, and PowerShell drives (PSDrives) by limiting where they can be read and changed. PowerShell uses scope rules to ensure that you do not inadvertently change an item that should not be changed.

In the second line for PROD\ avoid double quotes ("PROD\username") and replace them with single quotes ( 'PROD\username' )
