HandshakeError after run 'ws listen ws://localhost:8000/hello' on macOS about ws

Hello,
First of all, are you sure your server was started before the client run?
Did you try to upgrade the websocket version to the latest one?

Maybe I confuse the difference between echo-server and listen command. Since I can't see any response from echo-server when I send a text to the echo-server. However, even when I ran echo-server first, then run ws listen it still exit with ConnectionClosed error. Could you please introduce a typical scenario of how to set up a server can respond explicitly to the screen after receiving the text from a client? Thanks.
