Updating Active Directory via PowerShell

Hallo I got a question with my update script for my active directory
I am trying to update a user using .csv document
It’s for my understanding very simple but there is an error which I cant find out why it occurs.

My Script:

#Get CSV content
 $CSVrecords = Import-Csv "C:\scripts\test.csv" -Delimiter ";"
    
 #Create arrays for skipped and failed users
 $SkippedUsers = @()
 $FailedUsers = @()
    
 #Loop trough CSV records
 foreach ($CSVrecord in $CSVrecords) {
         $upn = $CSVrecord.UserPrincipalName
         $user = Get-ADUser -Filter "userPrincipalName -eq '$upn'"
         if ($user) {
                 try {
                         $user | Set-ADUser -Department $CSVrecord.Department -Company $CSVrecord.Company -ErrorAction STOP
                 }
                 catch {
                         $FailedUsers += $upn
                         Write-Warning "$upn user found, but FAILED to update."
                 }
         }
         else {
                 Write-Warning "$upn not found, skipped"
                 $SkippedUsers += $upn
         }
}

The Date that I am trying to use for the Update:

The Error message that I get: user found, but FAILED to update

Maybe I am blind but i cant find the error …

>Solution :

As mentioned in the comments, your catch block is hiding all terminating exceptions. Since you never output or inspect the given exception, there’s no way to tell what went wrong.

Change it to:

try {
    $user | Set-ADUser -Department $CSVrecord.Department -Company $CSVrecord.Company -ErrorAction STOP
}
catch {
   $FailedUsers += $upn
   Write-Warning "$upn user found, but FAILED to update: $_"
}

Inside the catch block, $_ will refer to the exception that was caught, so at least you now get a chance to see the underlying error message.
