You can do something similar as what is suggested on the npm package docs.

  // This is the default value of `retryStrategy`
  retryStrategy(times) {
    const delay = Math.min(times * 50, 2000);
    return delay;
  },
});

https://www.npmjs.com/package/ioredis#user-content-auto-reconnect

You'd need to send this redis configuration when creating the bull queue.

error solved successfully by adding tls

const imageQueue = new Bull("imageQueue", process.env.REDIS_TLS_URL, {
  redis: { tls: { rejectUnauthorized: false } },
});

bull uses ioredis to connect, and allows a third opts parameter in the Queue constructor. According to the source code it looks for a redis property within those opts.

You might try this to raise the retry limit to 100.

const opts = {redis:{maxRetriesPerRequest:100}}
const imageQueue = new Bull("imageQueue", process.env.REDIS_URL, opts);

But, also, you may be using Heroku's redis service more intensively than they allow for the free tier (if that's what you use).
