Close websocket connection?

[uLan08]

How would you properly close a websocket connection? Basically what I am trying to do is check if correct query string parameters are not present then I close the connection.
Here's what I am trying to do right now.

app.ws.use(route.get('/ws',  (ctx) => {
	const { foo, bar } = ctx.query
	if (!foo && !bar) {
		ctx.websocket.close(1000, 'Wrong or missing parameters')
		ctx.websocket.terminate()
                return
	}
}))

I am not really sure if this is correct because I keep on getting socket hang up messages and if I remove the return everything after the if statement still gets executed. I also tried using onclose event on the client but it never triggers.

I hope to add a reject function
