Error 500 when viewing invoices

Self-Hosted | v5
1

Hello everybody

First post, hope this is the right place to put it.

I just did an install of v5.0.56-C40 following the guide on Ubuntu 20.04, lxc on proxmox.
Installation on local network, hostname is invoiceninja.

When viewing an invoice i get an error 500.

larval.log doesn’t mention any problems.
/var/log/nginx/ininja.access.log gives the following message:

[02/Feb/2021:12:03:26 +0000] "GET /client/invoice/RZZ4b3YntOjA2Nr6kfC69X2tIQZty6nTsdCWHilNbghGHfYaHxi7yiHSw2H5lMCR/download_pdf HTTP/2.0" 500 1558 "https://invoiceninja/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.104 Safari/537.36"

During install, the PDF-test worked fine.
Could this be an nginx-misconfiguration ?

nginx is configured exactly like in the guide, except for the hostname.

Thanks in advance.

Hey there.

500 errors are usually written in laravel.log if not, it’s probably a permission problem.

Here’s how you can turn on in-browser errors (don’t forget to turn it off later because it might expose your credentials).

.env: APP_DEBUG=true (false should be default)

… and run the following:

php artisan optimize

Please let us know about the outcome.

Thanks for your reply.

APP_DEBUG is now set to true (Red notification showing in side bar)

This is the output from larval.log:

I hope this helps.

I enabled the expanded logging and got the following error message:

It looks like i’m missing something in my installation.
Does anybody know how which dependency this may be part of ?

Found the solution.
I was missing libgbm-dev.

apt install libgbm-dev

did the trick.

How did you enable the expanded logging?

I added EXPANDED_LOGGING=true to the .env file and ran php artisan optimize afterwards.

Thanks! Now I have an error message with a little bit more detail, but I don’t know how to fix it :frowning:

Well actually I have an idea. It says x64, but I have an x86 installation…I guess that is the problem…

Hey there, that could be a problem, definitely. You may want to provide your own Chrome/Chromium installed on your machine.

Then, provide globally available environment variable (not .env file):

SNAPPDF_EXECUTABLE_PATH=/path/to/your/chrome

If that works, please let me know, I’ll file a bug report on the snappdf repository & check 32bit compatibility. It should be supported as well :+1:
