504 Gateway Timeout, SnapPDF timeout, Chromium-browser errors #493

Open rombie18 opened 1 year ago

rombie18 commented 1 year ago

Setup information Running Invoice Ninja using docker-compose on a Raspberry Pi 3B+, arm64 v8.

Describe the bug The SnapPDF previews are not working and are timing out with error 504 Gateway Timeout.

To reproduce Steps to reproduce the behavior:

  1. Go to 'Edit invoice design'
  2. PDF preview does not generate and times out

Expected behavior A pdf preview or invoice should be generated.

Logs/Stacktrace When tying to manually save a website as pdf inside the dockerfiles-app container, the following error is generated. This explains the 504 Gateway Timeout. It seems that the chromium-browser process is causing the timeout.

~ $ ~/vendor/bin/snappdf convert --url https://github.com save.pdf -vvv
Downloading https://github.com and saving it to save.pdf

I was able to further narrow down the issue to be a timout of the Chromium browser used by the SnapPDF executable. When using the chromium-browser to try to print a pdf the following error is generated:

Heads up! Careful with the /usr/bin/chromium-browser --headless --disa.... command, this may freeze your system!

This log made me suspect there was a problem with dns resolution but when manually trying a nslookup and ping inside the container to github.com, this did resolve to an ip adress. At this point I am a bit stuck and I can't seem to find a reason why the chromium process causes these errors.

Docker/Kubernetes/Helm:

**Additional context**
My Raspberry Pi does sometimes have a substantial load on it which also could cause a timeout, however I don't think this is the problem here since the chromium-browser process generates errors.

@rombie18

I think you are on the right track, I believe this issue is a DNS resolution issue from within the container itself.

rombie18 commented 1 year ago

I did suspect this as well but when I do a ping or nslookup inside the container this does resolve to an ip address.
