Django.db.utils.DataError:整数超出范围（WebsocketsDjango通道）

Question

我正在部署一个使用django频道构建的django聊天应用程序。我已经创建了一个daphne.service文件来运行daphne命令。内容如下:

[Unit]
Description=WebSocket Daphne Service
After=network.target

[Service]
Type=simple
User=root
WorkingDirectory=/home/path/to/my/workingdirectory
ExecStart=/home//path/to/my/virtualenv/python
 /home/django/path/to/virtualenv/bin/daphne -b 0.0.0.0 -p 8001 myapp.asgi:application
Restart=on-failure

[Install]
WantedBy=multi-user.target

网页加载时websocket会连接，但我一发送消息，套接字就会关闭。检查daphne.service文件的状态后，我得到以下信息：

Nov 25 14:48:41 ip-172-31-34-249 daphne[1165]:return self._execute_with_wrappers(sql, params,many=False, executor=self._execute)

Nov 25 14:48:41 ip-172-31-34-249 daphne[1165]: django.db.utils.DataError: integer out of range

有什么想法吗这里可能有什么问题？ 谢谢
