I am calling PnP-GetWeb like this:

    [Microsoft.SharePoint.Client.SecurableObject]$Web = Get-PnPWeb -Connection $pnpConnection -ErrorAction SilentlyContinue
    if($null -eq $web) {
        throw "Could not get information for: $($pnpConnection.Url)"
    }

but when there is a 403 “Forbidden”, it only outputs this to stdout. There is no exception thrown and I don’t see a way to capture that error information unless I redirect stdout. It seems I need to capture its error output to a variable instead of to stdout so that I can format the error before logging it.

I this I can capture error output to a variable like this:

$output = Get-PnpWeb -Connection $pnpConnection 2>&1

but how do I both assign $web and $output?
