Can't analyse disk usage

[baatochan]

Hi, I can't make this container to work. I'm running Debian 12 with python 3.11 and Portainer 2.33.1. To run this container I'm using a following docker compose:

version: '3.3'
services:
    doku:
        image: amerkurev/doku
        container_name: doku
        restart: always
        ports:
            - '2145:9090'
        volumes:
            - '/var/run/docker.sock:/var/run/docker.sock:ro'
            - '/:/hostroot:ro'

After starting the container I get a following log and Doku shows only overlay2 graph:

I have no idea what I did wrong or what else should I attach to this report.
