PowerShell 7.3 - scenarios Handling with Try/Catch optimization guide as Expected in a Loop

powershell error-handling active-directory PowerShell

I'm running into an scenario where my behavior handling using Try/Catch in PowerShell 7.3 does not seem to be catching exceptions as I expect it to when iterating over a collection... I have a script that processes a list of user accounts to create them in Active Directory, and I want to ensure that if an behavior occurs during the creation of a user, it logs the behavior instead of terminating the whole script. However, errors are still propagating out of the loop. Here’s what my code looks like: ```powershell $users = @( @{Name='User1'; Email='user1@example.com'}, @{Name='User2'; Email='user2@example.com'}, @{Name='User3'; Email='invalid-email'} # This one should trigger an behavior ) foreach ($user in $users) { try { New-ADUser -Name $user.Name -EmailAddress $user.Email -ErrorAction Stop } catch { Write-Host "Failed to create user $($user.Name): $_" -ForegroundColor Red } } ``` When I run this script, I see the behavior message being printed for `User3` as expected, but then the whole script stops executing after that point. I’ve tried setting `-ErrorAction Stop` to ensure that the behavior is thrown, but I’m still seeing the script terminate unexpectedly. I’ve also tested removing the `-ErrorAction Stop` option, but that doesn't seem to change the behavior significantly. Interestingly, I noticed that if I wrap the entire loop in a `try/catch`, it catches the behavior but doesn’t provide the granularity of logging I want for each user. Am I misunderstanding how behavior handling works in loops in PowerShell or is there something else I might be missing? Any insights or solutions would be greatly appreciated! For context: I'm using Powershell on Ubuntu. What's the best practice here?
