I solved my issue by specifying tempDir to a usable temp directory, in my case Im using it on Heroku

In config/pdf.php

<?php

return [
	'mode'                  => 'utf-8',
	'format'                => 'A4',
	'author'                => '',
	'subject'               => '',
	'keywords'              => '',
	'creator'               => 'Laravel Pdf',
	'display_mode'          => 'fullpage',
	'tempDir'               => base_path('storage/app/mpdf')
];
