Why is my try catch error passing as successful even with -ErrorAction Stop on?

Question

Below is a simple Try Catch but when I was testing it, when successful it appears to file so I included a location which didnt exist into the variable to test the failure, but oddly even though the failure appears in the ISE window the out still shows as suceeded maing something isnt quite right with below, any ideas as Im lost at what is wrong.

## The location/filename where the Logs will be stored
$varfullpath = "I:\Dev\BI\Reference Data\Release_Event_log.txt"       
## The location/filename of the Source to copy from                                    
$sourceDirectory  = "C:\Users\Simon.Evans\Documents\Source Data\kljhkjlOS\"
## The location/filename of the Destination to copy to  
$destinationDirectory = "I:\Dev\BI\Projects\Powershell\Test Area\Source Data\OkjhkhDS\"
$Server = "CHH-BITEST"
$CurrentDate = Get-Date
try{
    Get-ChildItem -Path $sourceDirectory -File -Filter "*.csv" | Copy-Item -Destination $destinationDirectory -ErrorAction Stop
    Write-Log -Message "Copy from $sourceDirectory to $destinationDirectory suceeded"  -path $varfullpath             
}
catch{
    $Error[0] | Write-Log -path $varfullpath                                                                            
    Write-log -Message "Copy from $sourceDirectory to $destinationDirectory Failed"  -Level Error -path $varfullpath     
} 

Start-Process notepad $varfullpath  ## Opens the file immediately for review

Answer 1

The error is thrown by the get-childitemcommand.

Add the -ErrorAction Stop to this command like that:

Get-ChildItem -Path $sourceDirectory -File -Filter "*.csv" -ErrorAction Stop | Copy-Item -Destination $destinationDirectory -ErrorAction Stop
