WebSocketGateway中的WsException无法正常运行

Question

我在玩NestJs并遇到一个问题。我只是不能在WebSocket网关中引发异常。

一切都符合this doc page。

我试图加入

@UseFilters(new BaseWsExceptionFilter())

但是...没有帮助。

import {
    SubscribeMessage,
    WebSocketGateway,
    WebSocketServer, WsException,
} from '@nestjs/websockets';
import { Client, Server } from 'socket.io';

@WebSocketGateway()
export class EventsGateway {
    @WebSocketServer()
    server: Server;

    @SubscribeMessage('exception')
    exception(client: Client, data: number) {
        throw new WsException('Invalid credentials.');
    }
}

我像这样...

/home/innistry/Projects/nest-likbez/node_modules/rxjs/internal/util/hostReportError.js:4
[0]     setTimeout(function () { throw err; }, 0);
[0]                              ^

[0] TypeError: host.setType is not a function

由于早期版本中的错误，它不起作用。请使用npm update或yarn upgrade将依赖项更新到最新版本。
