Encountering "Error: connect ECONNREFUSED 127.0.0.1:6379..." when running Google Cloud Function connecting to a Redis Instance

Question

Im running a function to ingest data to a Redis instance. However, I am encountering an issue where I can't seem to connect to the client.

Here is the part of the code where it connects to the server.

const redis = require('redis');
require('dotenv').config;

        const REDISHOST = process.env.REDISHOST;
        const REDISPORT = 6379;
        const REDISAUTH = process.env.AUTHSTRING;

        const client = redis.createClient({
            port: REDISPORT,
            host: REDISHOST,
            password: REDISAUTH
        });

        await client.connect();

Here is the whole error message:

"Error: connect ECONNREFUSED 127.0.0.1:6379
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1278:16)
    at TCPConnectWrap.callbackTrampoline (node:internal/async_hooks:130:17)"

Any help would be appreciated. Thanks

I have tried using ioredis instead of redis but it shows a different error altogether.

It's trying to connect to localhost and Redis doesn't exist there. IF not given a hostname, this is the default behavior of Redis.

Looking at your code, this is probably because the REDISHOST environment variable isn't defined.
