Configuration file document is out of date

[gongyisheng]

I'm trying to run sandbox fusion using docker-compose, with a configuration file.
I follow the steps in document: https://bytedance.github.io/SandboxFusion/docs/docs/reference/config

Here's my setting up:

docker-compose.yaml

version: "3.9"

services:
  sandbox-fusion:
    image: volcengine/sandbox-fusion:server-20250609
    container_name: sandbox-fusion
    ports:
      - "8080:8080"
    environment:
      - SANDBOX_CONFIG=local
    volumes:
      - ./local.yaml:/root/sandbox/sandbox/configs/local.yaml
    stdin_open: true          
    tty: true             

local.yaml

online_judge:
  database:
    backend:
      type: none  # Don't connect to online database
    cache:
      path: memory  # Location of local cache sqlite database, here it's in memory
      sources:
        - type: local  # Read jsonl files from local folder as cache
          path: sandbox/tests/datasets/samples
  max_runner_concurrency: 3
runner:
  isolation: none
  cleanup_process: false
  restore_bash: false
  max_concurrency: 34
common:
  logging_color: true

I got following error:

uvicorn sandbox.server.server:app --host '' --port 8080

I look up the source code and found the doc is out of date, correct schema of configuration file is:
