"Message":"image not found: image:app.svg seems to be the problem here.

I guess there is something wrong with permissions or the symlink in /mnt/data apps.

I suspect that the apps folders permissions or rewrite doesn't fuction properly if the container is update by copying the new tar ball to /var/www

You should not copy anything to /var/www manually. Just use the new version of the container and launch the updated version.
