[mdeorue]

Hi guys,

When I remove the assets its works fine, but when I use them I got this error...

I have two assets (css and js).
<link rel="stylesheet" href="{{ url('/').mix('css/pdf.css') }}">
and
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.6.0/Chart.min.js"></script>
The view render without problem.

Can you help me pls, this problem repeats in Homestead (Windows) and Forge (Ubuntu Server).

Regards.

This is the Controller instance...

$invoiceFile = 'invoice_filename.pdf';
$pdf = \PDF::loadHTML($view->render())
            ->setOption('viewport-size', '1366x1024')
            ->setOption('enable-javascript', true)
            ->setOption('javascript-delay', 4000)
            ->setPaper('letter');
$pdf->download($invoiceFile);

Remove "https" from all the resources
<script src="http://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.6.0/Chart.min.js"></script>

I realize this is almost a year old, and unresolved still, but what if you can't remove https? As in the assets are ONLY available via https?

This issue occurs still on Ubuntu 20.04.1 (homestead latest) there is no longer a candidate for libssl1.0-dev

I'm still trying to resolve this myself, but not getting very far :(
