How Powershell Handles an Invalid attribute

I am expecting below code to throw an error..since Get-Childitem does not have Lastaccessed

try{    

Get-ChildItem | Where-Object { -not $_.PsIsContainer -and $_.lastaccessed -lt $date} -ErrorAction stop  
Write-Host "hello:"  
}
catch{  
Write-Host $($_)  
}  

But to my surprise,it does not

i did try to search,but cant find any satisfactory answers

>Solution :

You’d need to use Set-StrictMode for this to happen, more specifically version 2.0 or above:

Set-StrictMode -Version 2.0

If you look at the -Version parameter details you’d see:

• 2.0
  • Prohibits references to uninitialized variables. This includes uninitialized variables in strings.
  • Prohibits references to non-existent properties of an object.
  • Prohibits function calls that use the syntax for calling methods.
