PhantomJS script returns a blank web page

Question

I use phantomJS to create PDF files in PHP through the shell ( shell_exec ). The script works fine on a production server, and also works great if I connect the PhantomJS command directly to my terminal.

But this does not work when I run the script in the local local environment. I am wondering if there is a problem with permissions. I will not dive into the specification of my local environment for now, as I assume this is a high-level problem ...

The command to be executed through shell_exec() :

/usr/local/bin/phantomjs --ignore-ssl-errors=true --debug=true ../scripts/renderTeamProfile.js https://127.0.0.1/app_dev.php/pdf/enterprise-lpc-enterprise/profile/render /private/var/tmp/pjsK2N16E.pdf

php code:

  public function pdfResponse($url, $script, $remote_filename) { $tempFile = tempnam('/tmp', 'pjs'); // The extension specifies output format. Use pdf $tempFilePdf = $tempFile . '.pdf'; rename($tempFile, $tempFilePdf); # nginx should restrict access to the localhost URL $urlLocal = preg_replace('/^https:..[^\/]+/', 'https://127.0.0.1', $url); $phantomJs = $this->container->getParameter('testsite.phantomjs_cmd'); $command = $phantomJs.' --debug=true '.$script.' '.$urlLocal.' '.$tempFilePdf; $output = shell_exec($command); $content = file_get_contents($tempFilePdf); $response = new Response($content, 200); $response->headers->set('Content-Type', 'application/pdf'); $response->headers->set('Content-Disposition', ('inline; filename="' . $remote_filename . '"')); return $response; }

It turns out another version of phantomjs was installed locally installed on the prod server. Interestingly, the error occurred with the newer version (2.0.0) and 1.9.8.
