Websocket Error

[fenibofubara]

Hello family, so I am trying to use Websocket in my adonis "version": "4.1.0", app.
I have followed all the steps here: https://legacy.adonisjs.com/docs/4.1/websocket
This has also been added in my server.js file: .wsServer() // boot the WebSocket server.

However, I get the following error, whenever I want to run the app using: adonis serve --dev

Here is the error:

Error: Cannot find module 'Adonis/Addons/Ws'
Require stack:

• /home/fenibo/Desktop/droomwork/droomworkApi/node_modules/require-stack/src/index.js
• /home/fenibo/Desktop/droomwork/droomworkApi/node_modules/require-stack/index.js
• /home/fenibo/Desktop/droomwork/droomworkApi/node_modules/@adonisjs/fold/src/Ioc/index.js
• /home/fenibo/Desktop/droomwork/droomworkApi/node_modules/@adonisjs/fold/index.js
• /home/fenibo/Desktop/droomwork/droomworkApi/server.js

What do I do to debug this so I can move on please, I have been stuck here for 2 days now
