400 Bad Request with Adonisjs websocket

Question

I'm runing a localhost adonisjs project with a websocket. I followed the adonis get started here. Everything in the server looks ok, but when I tried to connect in my react-native application a got this error:

{
  "isTrusted": false,
  "message": "Expected HTTP 101 response but was '400 Bad Request'",
}

This is my cliente code:

const ws = new WebSocket("ws://192.168.0.11:3333")

ws.onopen = () => {
    ws.send(JSON.stringify({
        t: 1,
        d: { topic: 'prelista:5999c0ea-6bbb-4e0f-9496-f62658bbac5' }
    }))
}

ws.onmessage = (e) => {
    console.log(e)
}

ws.onerror = (event) => {
    console.log(event)
}

This is my server code:

'use strict'

const Ws = use('Ws')

Ws.channel('prelista:*', ({ socket }) => {
  console.log(socket.topic)
})

I found my mistake. Whe we use Adonis websocket on the server side, we need to add /adonis-ws in the end of ws path. Well, changed this const ws = new WebSocket("ws://192.168.0.11:3333") to this const ws = new WebSocket("ws://192.168.0.11:3333/adonis-ws")

worked now
