AbortError: Redis connection lost and command aborted. It might have been processed.

Here is my code

and this is the log

I got this error on my GCP(GAE and Redis) and don't know how to resolve it. Please help.

Environment

Node.js Version: 12.x.x

Redis Version: 5.o

Platform: macOS Big Sur 11.2


const rateLimit = require('express-rate-limit');
const redis = require('redis');
const RedisStore = require('rate-limit-redis');

const REDIS_CONFIG = {
  PORT: 6379, // Replace with your Redis port
  HOST: 'localhost', // Replace with your Redis host
};

const RATE_LIMIT = {
  timerange: 15 * 60 * 1000, // 15 minutes in milliseconds
  count: 100, // Max requests
  message: 'Too many requests, please try again later.',
};

let apiLimiter;

// Create Redis client with error handling
const client = redis.createClient(REDIS_CONFIG.PORT, REDIS_CONFIG.HOST);

client.on('error', (err) => {
  console.error('ERR:REDIS:', err);
});

client.on('connect', () => {
  console.info('INFO:REDIS: Connected!');
});

// Handle Redis connection error and retry logic
client.on('reconnecting', () => {
  console.info('INFO:REDIS: Reconnecting...');
});

client.on('end', () => {
  console.info('INFO:REDIS: Connection closed');
});

// Create rate limiter
apiLimiter = rateLimit({
  store: new RedisStore({
    client: client,
    passIfNotConnected: true, // This option allows to pass if the Redis server is not connected
  }),
  windowMs: RATE_LIMIT.timerange,
  max: RATE_LIMIT.count,
  keyGenerator: (req) => req.ip, // Use req.ip for rate limiting
  message: { status: 'rateLimit', msg: RATE_LIMIT.message },
});

// Export apiLimiter to use in your Express app
module.exports = apiLimiter;
