Trying to deploy my application on render.com, trying connecting to db via internal url, connection is getting refused, app trying a local connection

Question

I'm trying deploying my application wherein im using workers and ques for jobs, trying to connect the redis instance to my application , connection is getting refused. I thik app still trying to hit a local connection. Here is my redis.js in config

const redis = require('redis');

// Redis configuration options
const redisConfig = {
  url: 'redis://red-cjds7cavvtos73bpvvn0:6379',
  host: 'red-cjds7cavvtos73bpvvn0'
};
console.log('redis config started with redis url: ',redisConfig.url)
// Create a Redis client
const client = redis.createClient(redisConfig);
console.log("client added: ",client)
// Event listeners for Redis client
client.on('connect', () => {
  console.log('Connected to Redis');
});

client.on('error', (error) => {
  console.error('Error connecting to Redis:', error);
});
console.log('exporting the connection')

// Export the Redis client
module.exports = client;

following is my import of the config file in server's root index

const express = require('express')
const app = express();
const redisConnection=require('./config/redis')
const path = require('path')
const port = 7000
const db = require('./config/mongoose')

following is the error in the deployement logs on render:
