[Question] MaxRetriesPerRequest Error

Description

The maxRetriesPerRequest error only during production, everything works fine on my local setup despite using the redis connection string (Upstash: tls turned off).

I found a solution to turn the maxRetriesPerRequest setting to null but then it just hangs indefinitely.

I would really like to know what i could be doing wrong. Thank you.

Minimal, Working Test code to reproduce the issue.

import Redis from "ioredis";
import Queue from "bull";

const REDIS_URL = process.env.REDIS_URL as string;
const client = new Redis(REDIS_URL, {
  lazyConnect: true,
  enableReadyCheck: false,
  maxRetriesPerRequest: 3,
});
const subscriber = new Redis(REDIS_URL, {
  enableReadyCheck: false,
  maxRetriesPerRequest: null,
});

const redisOptions = {
  // redisOpts here will contain at least a property of
  // connectionName which will identify the queue based on its name
  createClient: function (type: string, redisOpts: any) {
    switch (type) {
      case "client":
        return client;
      case "subscriber":
        return subscriber;
      case "bclient":
        return new Redis(REDIS_URL, {
          ...redisOpts,
          enableReadyCheck: false,
          maxRetriesPerRequest: null,
        });
      default:
        throw new Error("Unexpected connection type: ", type);
    }
  },
};


 const queue = new Queue("queuer",redisOptions);


async function addToQueue(data) {
  const job = await queue.add(data);
  return job;
}


queue.process(async (job) => {
  console.log(job.data)
});

Bull version

^4.10.2
