500 error when editing Invoice Template

I just migrated my installation to a new server that is running on OpenLitespeed with PHP 7.4 (a runcloud server)

I can view PDFs and generate PDFs fine using snappdf. I have checked and I believe I have all required modules installed.

I have also checked and I do not have mod_security running on this domain.

When I edit the PDF invoice template, a 500 error occurs:

[2021-07-23 18:29:10] production.ERROR: The process has been signaled with signal “6”. {“userId”:1,“exception”:"[object] (Symfony\Component\Process\Exception\ProcessSignaledException(code: 0): The process has been signaled with signal “6”. at /home/invoices/webapps/invoiceninja/vendor/symfony/process/Process.php:436)


Thanks for reporting this!

@david any thoughts


I’m not sure, this sounds like an issue with the system (via the app) being unable to execute snappdf/chrome to generate the PDF

Was this issue ever resolved?
I’m having the exact error on openlitespeed and invoiceninja v5 except I cannot view or generate pdfs.
