File transfer in docker-compose setup

[LeventeLantos]

Hi,
I am working on a pet project where I would like to only use a docker-compose stack for distributing data, this is my stack:
`version: '3.8'
services:
distributor:
build: .
volumes:
- ./distributor-data:/app/data
- ./torrent-files:/app/torrent
command: ["./distributor"]
ports:
- "8080:8080"
- "42069:42069"
- "6881:6881/udp"
networks:
vnet:

receiver1:
build: .
volumes:
- ./receiver1-data:/app/data
- ./torrent-files:/app/torrent
command: ["./receiver", "/app/data/myfile.torrent"]
depends_on:
- distributor
networks:
vnet:

receiver2:
build: .
volumes:
- ./receiver2-data:/app/data
- ./torrent-files:/app/torrent
command: ["./receiver", "/app/data/myfile.torrent"]
depends_on:
- distributor
networks:
vnet:

receiver3:
build: .
volumes:
- ./receiver3-data:/app/data
- ./torrent-files:/app/torrent
command: ["./receiver", "/app/data/myfile.torrent"]
depends_on:
- distributor
networks:
vnet:

networks:
vnet:
driver: bridge

I'm using magnet links, but I'm getting a lot of errors like this:

Is it even possible to make this work inside a docker-compose setup?
Thanks in advance

Those are debugging messages, have you set Debug true in your ClientConfig?
