I cannot use Websocket package on NestJS

I'm trying to work with websockets on Nestjs, i install the dependencies

yarn add @nestjs/websockets @nestjs/platform-socket.io

I generated a example resource for the websockets

nest g res messagesWs --no-spec

Then this message shows up in my terminal

TypeError: this.metadataScanner.getAllMethodNames is not a function

This is a capture from the problem

What can i do? PD: sorry for my bad english

I search for that function getAllMethodNames but i didn't get anything

Work for me:

Get @nestjs/core version in pnpm-lock.yaml

Then install @nestjs/platform-socket.io and @nestjs/websockets as same version of @nestjs/core

Or upgrade all packages about nestjs to latest, pnpm up

@nestjs/core and @nestjs/websockets versions should always be in sync. For example, if the latest version of your locally installed @nestjs/websockets package is 9.3.6, then you have to make sure that @nestjs/core is also on 9.3.6.

Once you fix this up, the error will go away.

I had the same problem. I solved it by downgrading a few versions.

From

"@nestjs/platform-socket.io": "9.3.6", "@nestjs/websockets": "9.3.6"

to

"@nestjs/platform-socket.io": "9.1.6", "@nestjs/websockets": "9.1.6"
