Set "read_only" as false in docker-compose.yml:

  judge-server:
    image: registry.cn-hangzhou.aliyuncs.com/onlinejudge/judge_server
    container_name: judge-server
    restart: always
    read_only: false
    tmpfs:
      - /tmp
    volumes:
      - ./data/backend/test_case:/test_case:ro
      - ./data/judge_server/log:/log
      - ./data/judge_server/run:/judger
    environment:
      - SERVICE_URL=http://judge-server:8080
      - BACKEND_URL=http://oj-backend:8000/api/judge_server_heartbeat/
      - TOKEN=CHANGE_THIS
