PDF Export didn't work (Chromium headless)

[wolf-in-sheeps-clothing]

Describe the bug

If I choose Download -> PDF the following error is shown:

Can't export

#0 /usr/share/icingaweb2/library/vendor/Zend/Controller/Action.php(507): Icinga\Module\Reporting\Controllers\ReportController->downloadAction()
#1 /usr/share/php/Icinga/Web/Controller/Dispatcher.php(76): Zend_Controller_Action->dispatch(String)
#2 /usr/share/icingaweb2/library/vendor/Zend/Controller/Front.php(937): Icinga\Web\Controller\Dispatcher->dispatch(Object(Icinga\Web\Request), Object(Icinga\Web\Response))
#3 /usr/share/php/Icinga/Application/Web.php(300): Zend_Controller_Front->dispatch(Object(Icinga\Web\Request), Object(Icinga\Web\Response))
#4 /usr/share/php/Icinga/Application/webrouter.php(104): Icinga\Application\Web->dispatch()
#5 /usr/share/icingaweb2/public/index.php(4): require_once(String)
#6 {main}

Expected behavior

PDF Export should work :-)

Ensure that pdfexport dependencies are fulfilled, specifically chrome. https://github.com/Icinga/icingaweb2-module-pdfexport/blob/master/doc/02-Installation.md

Hi Michael,

yes, all dependencies are fulfilled! See my comment -> Your Environment -> Dependent module versions

But I think I'm not alone: Icinga/icingaweb2-module-pdfexport#7

Same here. Using Chromium instead of Chrome but getting the same.
Double check all requirements. Same problem.
ipl -> latest release
reactbundle -> latest release
icingweb2 -> latest release
RHEL 7 latest release
Apache 2.4 latest release

[lokidaibel]

So chromium dont work. Chrome does.

[dnsmichi]

Ok, might need further tests then. I couldn't get chromium-headless from EPEL to work, my last debug point where some missing library references after I switched to Icinga 2.11 again.

[wolf-in-sheeps-clothing]

To clarify: I installed Chrome Stable.

google-chrome --version
Google Chrome 73.0.3683.103

Same here, with the diffenrence that Debian Stretch is used.
Installed google-chrome-stable today
But I think I found the reason: In Debian the google-chrome bin is linked to /usr/bin/google-chrome instead of the expexted /bin/google-chrome (which is hardcoded in library/Pdfexport/ProvidedHook/Pdfexport.php)
Create a link in /bin an it works.

[wolf-in-sheeps-clothing]

Yeah, that's the solution (quick and dirty). After setting the symlink everything looks fine
But in the long run, the PDF module should be adapted.
Thanks a lot.

[wolf-in-sheeps-clothing]

I think we can close this.

Look at: Icinga/icingaweb2-module-pdfexport@2d34431

Now you can edit the binary path to "Google Chrome" in the PDF Export Modul Frontend (Master)!
Set it to /usr/bin/google-chrome (Debian / Ubuntu) and everything works fine.

Many thanks to @lippserd -> Thumbs up!
