Timeout exceeded exception

[Vercryger]

I have read #221 and #169 and there is no clear solution for this issue, I only get this exception no matter what content is at /reportendpoint:

The process "/usr/local/bin/wkhtmltopdf --lowquality 'http://localhost:8000/api/v1/report' '/var/folders/2m/5k5yt7_93pj2bmm7my3c0tzc0000gn/T/knp_snappy5a31edc8ab61e5.34915099.pdf'" exceeded the timeout of 60 seconds.

If I try to run this using the wkhtmltopdf cli, everything work just fine almost instantly:

$ wkhtmltopdf http://localhost:8000/api/v1/report out.pdf

Did you find a solution to this? I'm experiencing something similar.

Hi @williamhector, I'm afraid not 😞 We decided to migrate everything about printing to a new app with Electron.

Our problem turned out to be an issue with the way we were running wkhtmltopdf, not with snappy or wkhtmltopdf itself.
We are running an Azure web server (CentOS-ish) and had a bash script at /usr/local/bin/wkhtmltoimage that simply ran:

#!/bin/bash
xvfb-run /bin/wkhtmltoimage "$@"

It would run fine from the command line, even when run as our Apache user from command line, however, when called from our PHP application, it would timeout and hog memory until it crashed Apache.

When I changed it to:

#!/bin/bash
xvfb-run /bin/wkhtmltoimage --use-xserver "$@"

it started working from our PHP app as well.

I'm not that knowledgeable on X server command and that --use-xserver option isn't mentioned in the wkhtmltopdf/image command line usage documentation, at least in our version of it.
