函数计算中，为啥我从环境变量读到了阿里云的redis配置，在nodeJs环境中调用报了这个错？

代码如下：exports.initialize = async (context) => {
console.log("initialize");
const type_env = process.env.TYPE;
console.log(type: ${type_env});

if (type_env === "redis") {
    const REDIS_HOST = process.env.REDIS_HOST;
    const REDIS_PORT = parseInt(process.env.REDIS_PORT, 10) || 6379;
    const REDIS_PASSWORD = process.env.REDIS_PASSWORD;

    if (!REDIS_HOST || !REDIS_PASSWORD) {
        throw new Error("REDIS_HOST, REDIS_PORT, REDIS_PASSWORD must be set");
    }
    redis_pool = redis.createClient({
        host: REDIS_HOST,
        pass: REDIS_PORT,
        password: REDIS_PASSWORD,
        maxRetriesPerRequest: 3,
        enableReadyCheck: true,
    });

    // 使用promisify处理异步操作
    redis_pool.connect = promisify(redis_pool.connect).bind(redis_pool);
    await redis_pool.connect();
    if (await redis_pool.ping() === 'PONG') {
      console.log('Connected to Redis successfully');
    } else {
      console.error('Failed to connect to Redis');
    }
    console.log("initialize redis_pool");
}

};
