RedisIoAdapter没有调用签名

在实现 RedisIoAdapter 如何在https://docs.nestjs.com/websockets/adapter 中进行描述后，我试图将 socket.io-redis 作为调度程序

import { IoAdapter } from '@nestjs/platform-socket.io';
import * as redisIoAdapter from 'socket.io-redis';

export class RedisIoAdapter extends IoAdapter {
  createIOServer(port: number, options?: any): any {
    const server = super.createIOServer(port, options);
    const redisAdapter = redisIoAdapter({ host: 'localhost', port: 6379 });

    server.adapter(redisAdapter);
    return server;
  }
}

出现错误redisIoAdapter此表达式不可调用。

"socket.io-redis": "^6.0.1"
"@nestjs/platform-socket.io": "^7.6.4",
"@nestjs/websockets": "^7.6.4",
