woodpecker-server fails with "index.html: file does not exist"

Hello, I was glad I found your work ; I'm trying to use woodpecker on an armv7 server. It runs latest Arch and podman.

I have the same configuration on my computer (only, it's an x86_64). If I run the following docker-compose.yml file, the agent succeeds in connecting with the server. But running the same docker-compose.yml, only with your images instead of woodpecker's ones, it fails - see the attached log. In short, when the server finally becomes ready and the agent's request apparently reaches it, it fails with panic: open index.html: file does not exist.

The docker-compose file I ran on armv7 :

# docker-compose.yml
version: '3'

services:
  woodpecker-server:
    #image: woodpeckerci/woodpecker-server:latest
    image: florianpiesche/woodpecker-server:latest

      - "8000:8000"
