我正在从邮递员 http://localhost:5005/conversations 调用RASA API 但这给我一个错误。

我已经创建了跟踪器存储区以在SQL中存储聊天，并且正在使用以下命令来运行rasa。

rasa run --cors "*" -m models --enable-api --log-file out.log --endpoints endpoints.yml --auth-token thisismysecret --debug

我不知道哪里出问题了。

我期待以下输出。

```[

{

    "conversation_id": "string","latest_event_time": 0,"latest_input_channel": "string","intents": 

[],"actions": 
[],"minimum_action_confidence": 0,"in_training_data": true,"policies": 
[],"n_user_messages": 0,"flagged_messages": 
[],"unflagged_messages": 

        []
    }

]```

endpoints.yml

```action_endpoint:
  url: "http://localhost:5055/webhook"
