So i am running the tutorial script as in the readme.md and am receiving this error:

Notice: Trying to get property 'size' of non-object in /Users/devleaf/OneDrive/Work/Devleaf/Development/devleaf.local:5757/build/vendor/dompdf/dompdf/src/Dompdf.php on line 735

I used composer to install the library and my code is as follows:

use Dompdf\Dompdf;
ob_clean();
$pdf = new Dompdf();
$pdf->set_option('isHtml5ParserEnabled', true);
$pdf->loadHtml('Hello World');
$pdf->setPaper('A4', 'landscape');
$pdf->render();
$pdf->stream();
exit('Pdf should run');

I have also tried:
$pdf->loadHtml('<p>Hello World</p>');
which does not lead to any success.

My setup is as follows:

OS: MacOS 10.13.3
Programs: MAMP PRO 4.4.1, Codekit 3.5.2
PHP Version: PHP 7.2.1

Any help would be appreciated. As there is nothing which should stop the tutorial code from working except a bug in the code.

Not sure about the notice, maybe related to #1705?

Which version of dompdf are you using? We were seeing a lot of "block-level parent not found" errors recently and it was due to the version of libxml (#1560). 0.8.2 included a patch against that particular issue.

Thanks for your reply bsweeney. Yeah the notice shouldn't be anything to worry about, it was more so the fatal error.

Currently running v0.8.2 of dompdf with the following requirement versions:
sabberworm/php-css-parser: 8.1.0
phenx/php-svg-lib: v0.3
phnnx/php-font-lib: 0.5.1
and as stated previously php v7.2.1. Tried doing a bit of digging around but can't seem to notice any issues with conflict.

Thanks in advance for your help.
