permission denied error with spatie/browsershot run

In my laravel 5 app I installed spatie/browsershot 3.37 and I got error on my server:

    The command "PATH=$PATH:/usr/local/bin NODE_PATH=`npm root -g` node '/var/www/html/the-box-booking/vendor/spatie/browsershot/src/../bin/browser.js' '{"url":"file:\/\/\/tmp\/1253868703-0501081001593084129\/index.html","action":"pdf","options":

where /var/www/html/the-box-booking - app root

and with code :

$save_to_file     = 'generate_profile_card_' . Session::getId() . '_' . $filename_to_save;


if (strtolower($option_output_file_format) == 'pdf') {
    Browsershot::html(htmlspecialchars_decode($pdf_content))
               ->showBackground()
               ->save($save_to_file);  // ERROR POINTING THIS LINE

looks like I lack some permittions. Which ?

Thanks!
