python - アウトバーンでコンポーネントの役割を設定する方法

Question

クロスバー 0.11.1 を使用しており、アウトバーン コンポーネントに特定の役割を使用させたいと考えています。以下のように、「ロール」属性をコンポーネントに追加すると:

"components": [
        {
           "type": "class",
           "classname": "hello.hello.AppSession",
           "realm": "realm1",
           "role": "anonymous",
           "transport": {
              "type": "websocket",
              "endpoint": {
                 "type": "tcp",
                 "host": "127.0.0.1",
                 "port": 8080
              },
              "url": "ws://127.0.0.1:8080/ws"
           }
        }
     ]

実行時にこのエラーが発生しますcrossbar start
