How to get the line number of error in PowerShell

here's another useful way to capture a detailed exception

try
{
    throw "fdsfds"
}
catch
{
    Write-Error ($_.Exception | Format-List -Force | Out-String) -ErrorAction Continue
    Write-Error ($_.InvocationInfo | Format-List -Force | Out-String) -ErrorAction Continue
    throw
}

I figured out what the issue was:

Instead of:

$e = $_.Exception
#this is wrong
$line = $_.Exception.InvocationInfo.ScriptLineNumber
$msg = $e.Message 

Write-Host -ForegroundColor Red "caught exception: $e at $line"

It should be

$e = $_.Exception
$line = $_.InvocationInfo.ScriptLineNumber
$msg = $e.Message 

Write-Host -ForegroundColor Red "caught exception: $e at $line"
