If you try to run the following command directly does it give you any kind of errors?

$ GOOS=js GOARCH=wasm go build -o lib.wasm "masquerade.go"

If not try to hard reload the browser window with CTRL-R.

No errors are running the go build command, CTRL-R does not change anything.

I can get the correct response with curl, I am still working on this.

I found the root cause and can play the demos now.

Port 5000 is actually used by Control Center (AirPlay service) in macOS from Monterey, so the browser will return 403 if you try to access it, but the curl is not affected by this somehow.

If I try to use ports like 6000 or 6666, the browser will return an err_unsafe_port error, that's because there are some ports are blocked.

We should either use an unblocked port or add the --explicitly-allowed-ports option to the browser startup command.
