Unable to render PNG : `convert: unable to open image '/output/cover.png.temp': No such file or directory`

Hi, I've tried to install and use the docker container on a RPi3 with Portainer. Once the container is online, I cannot see any picture neither on the webpage, nor on the output directory.

Here is the error I get in logs :

I have tried with multiple websites (including the Google homepage) and it seems I get here every time... Please accept my apologies if I miss something in reporting this issue. Antoine
