Import-CSV to Get-ADUser

Question

I am trying to make a very simple script work that reads a CSV with 100 SamAccountName/Identities into a variable and then returns AD Users with all Objects from Get-ADUser.

The CSV only contains usernames (1 each line) so essentially it could also be a simple text file.

I feel like I'm very close but I can't make it work for some reason.

$users= (Import-CSV 'C:\Temp\users.csv') # <-- Doesn't work

#$users= "backupservice","name01" <-- This Works

ForEach ($user in $users) 

{
Get-ADUser $user -Properties *
}

Here's the error message when I am trying to read the CSV into the loop:

Get-ADUser : Cannot validate argument on parameter 'Identity'. The Identity property on the argument is null or empty.
At line:8 char:16
+     Get-ADUser $user -Properties *
+                ~~~~~
    + CategoryInfo          : InvalidData: (:) [Get-ADUser], ParameterBindingValidationException
    + FullyQualifiedErrorId : ParameterArgumentValidationError,Microsoft.ActiveDirectory.Management.Commands.GetADUser

Okay, so I have an issue with parameter binding but I am not sure how to fix it.

I would appreciate any input/insight you could give me.

Thank you!

I actually just now took the original CSV (which had two columns [SamAccountName and UPN]) and fixed it just now with the following code:

    $users = (Import-CSV "C:\Temp\Test001.csv" | Select SamAccountName -ExpandProperty SamAccountName)

    ForEach ($user in $users) 

    {

    Get-ADUser $user -Properties * #| Export-CSV 'C:\Temp\users_expanded.csv'-Append
    
    } 

Is there a better way to do this? The journey continues.
