PDF Export stopped working after update of Icinga

[JensBavenmark]

Describe the bug

After update to Icinga Web 2.9.3 and Icinga 2.13.1-1 the PDF export stopped working. All other exports work.
Also if i try to save config for pdfexport in Chrome field (Chrome headless is run on another hosts) I also get an error.

Error code when creating PDF:

Fatal error: Uncaught ErrorException: Uncaught ErrorException: file_get_contents(/public/css/themes/default.less): failed to open stream: No such file or directory in /usr/share/php/Icinga/Web/StyleSheet.php:185 Stack trace: #0 [internal function]: Icinga\Application\ApplicationBootstrap->Icinga\Application{closure}(2, 'file_get_conten...', '/usr/share/php/...', 185, Array) #1 /usr/share/php/Icinga/Web/StyleSheet.php(185): file_get_contents('/public/css/the...') #2 /usr/share/php/Icinga/Web/StyleSheet.php(124): Icinga\Web\StyleSheet->collect() #3 /usr/share/php/Icinga/Web/StyleSheet.php(208): Icinga\Web\StyleSheet->__construct() #4 /usr/share/icingaweb2/application/layouts/scripts/pdf.phtml(18): Icinga\Web\StyleSheet::forPdf() #5 /usr/share/php/Icinga/Web/View.php(235): include('/usr/share/icin...') #6 /usr/share/icingaweb2/library/vendor/Zend/View/Abstract.php(877): Icinga\Web\View->_run('/usr/share/icin...') #7 /usr/share/icingaweb2/library/vendor/Zend/Layout.php(786): Zend_View_Abstract->render(NULL) #8 /usr/share/ici in /usr/share/icingaweb2/library/vendor/Zend/Controller/Plugin/Broker.php on line 259

Please try the latest master instead. We'll release a new version this week, it'd be nice to know that you don't have these issues with the master 😉
