我正在写一个多人游戏包使用websockets。我在包中有一个服务器文件和一个客户机文件，并设置了两个单独的测试文件来测试包，一个是服务器，一个是客户机。
我的问题是，当运行服务器并通过客户端连接到它时，它会连接，然后立即断开连接。当查看回溯时，没有明显的原因可以解释为什么它断开连接。
回溯：

我查了OSError: [WinError 6] The handle is invalid和TypeError: cannot pickle '_asyncio.Future' object没有结果。我在其他地方问过这个问题，没有得到答案。我试着连接到服务器，并发送一些测试数据。
任何帮助感激不尽。
