Please help me. I spent several days trying to address this, and my task’s deadline is approaching. I really need your help.

@AJackTi
I have resolved this issue with these changes. The key is to overwrite release method and check if lock expired.

import Redlock from 'redlock'
import { redis } from '../storage/redis'

export const redlock = new Redlock([redis], {
  // The expected clock drift; for more details see:
  // http://redis.io/topics/distlock
  driftFactor: 0.01, // multiplied by lock ttl to determine drift time
  // The max number of times Redlock will attempt to lock a resource
  // before erroring.
  retryCount: 30,
  // the time in ms between attempts
  retryDelay: 2000, // time in ms
  // the max time in ms randomly added to retries
  // to improve performance under high contention
  // see https://www.awsarchitectureblog.com/2015/03/backoff.html
  retryJitter: 200, // time in ms
  // The minimum remaining time on a lock before an extension is automatically
  // attempted with the `using` API.
  automaticExtensionThreshold: 500, // time in ms
})

// Save the original acquire method
const originalAcquire = Redlock.prototype.acquire

// Override the release method for all lock instances
Redlock.prototype.acquire = async function (...args) {
  const duration = args[1] // this is a duration value

  // use the duration to create additional settings
  args[2] = {
    retryCount: Math.ceil((duration / 2_000) * 1.5),
    retryDelay: 2_000,
    ...args[2],
  }

  return originalAcquire.apply(this, args) // Call the original release method
}

// Save the original release method
const originalRelease = Redlock.prototype.release

// Override the release method for all lock instances
Redlock.prototype.release = async function (...args) {
  const now = new Date().getTime()

  if (args[0] && args[0].expiration > now) {
    // Check if the lock still exists
    return originalRelease.apply(this, args) // Call the original release method
  }

  return {
    attempts: [],
  }
}
