PDF-Export Application Problem (Experimental PDF-Export with Docker)

Help / Discuss
20

Hello to you both,
I have tested both, with and without docker. One is installed on my Synology with docker and I test it like you described it @jwielsch. (everything internal Docker)
I test with changing xwiki.porperties or not and installing zenika/alpine-chrome:latest or not.
I get this error on Docker Versions:

And the other test is under Ubuntu 20.04 without docker I described in my early post: PDF Template - Content of Page based on encyclopaedia

I know that it is experimental, and I would like to test it to help you.
I can wait for a new version and test it again.

Many thanks in advance
