Question

given the script.

$foo = @("bar")

try {
    $foo | ForEach-Object {
        Join-Path $null $null
    }
} catch {
    $_.InvocationInfo.Line
}

will print

$foo | ForEach-Object {

but I would like

Join-Path $null $null

How can I get where the exception was actually raised?

Answer 1

This will get you the actual line:

$_.Exception.CommandInvocation.Line

and exception message:

$_.Exception.Message

and line number:

$_.Exception.Line

and offset (column):

$_.Exception.Offset

So you could make a helpful little message:

} catch {
    $msg = "Failed to do something. Failed on line number '{0}' column '{1}' ('{2}'). The error was '{3}'." -f 
        $_.Exception.Line, $_.Exception.Offset, $_.Exception.CommandInvocation.Line.Trim(), $_.Exception.Message
    Write-Error $msg
}
