Django頻道JsonWebsocketConsumer self.send_json（）錯誤

Question

我正在編寫一個消費者，該消費者在通過via self.send_json（）發送后發送一個對話列表和一個配置文件對象（聯系人），此錯誤顯示出來，我真的不知道發生了什么，想知道您是否可以提供幫助

錯誤：

Consumers.py：

```python
    class LoadConsumer(JsonWebsocketConsumer):

        def connect(self):
            if self.scope['user'].is_authenticated:
                self.accept()
            else:
                self.close()

        def receive_json(self, content, **kwargs):
            if content['command'] == "CHAT":
                name = content['name']
                data = self.load_conversation_contact(name)
            else:
                data = {"success": False, "errors": "no such command"}
            self.send_json(data) # the error happens here

        def load_conversation_contact(self, name):
            conversation = self.load_conversation(name)
            contact = self.load_contact()
            return {
                "success": True,
                "conversation": conversation['conversation'],
                "contact": contact['contact'],
            }

    def load_conversation(self, name):
        conversation = Conversation.objects.filter(name=name).first()
        if conversation:
            serializer = ConversationSerializer(conversation)
            data = serializer.data
            return {"success": True, "conversation": data}
        return {"success": False}
```

資料：

```python
    {'success': True, 'conversation': {'type': 'couple', 'name': 
    'conversation_8', 'contacts': [OrderedDict([('first_name', 'limbi'), 
    ('last_name', 'salah'), ('location', 'London, UK'), ('contact_pic',

    'dude'), ('location', 'London, UK'), ('contact_pic',

    simply dummy text of the printing and typesetting industry.', 
    'last_message_date': 'Yesterday', 'message_set': 
    [OrderedDict([('content', 
   'Lorem Ipsum is simply dummy text of the printing and typesetting

    'user': 
    'limbi@main.com'}}
```

我試過：1.調試以查看出什么問題2.更改名稱的值

Answer 1
