Chapter 1 Websockets ServeHTTP:websocket: the client is not using the websocket protocol: 'upgrade' token not found in 'Connection' header

Code followed as per book. Also verified by cloning the code from this repo. Issue persists.

Occurs when trying to open /room path from the browser, also leading the code to crash.

$ go run .
2022/06/28 16:23:28 Starting web server on :8080
2022/06/28 16:23:56 ServeHTTP:websocket: the client is not using the websocket protocol: 'upgrade' token not found in 'Connection' header
exit status 1

Is the room service supposed to run in background? If so, then this issue would be pointless and just my misunderstanding. Issue can be closed if that is the case.
