[Bug]: job.processedBy is undefined after second worker run

[dimonnwc3]

Version

v5.40.2

Platform

NodeJS

What happened?

When passing name to worker options, it's supposed to show this name on the job.processedBy property. It works for the first time but doesn't for all sequentially runs. It can be reproduced only when there is a timeout inside worker function.

How to reproduce.

queue.ts

import { Queue } from "bullmq"

const q = new Queue("super-task", { connection: { url: "localhost" } })

while (true) {
  await q.add("super-task", {})
  await new Promise((res) => setTimeout(res, 5000))
}

worker.ts

import { Worker } from "bullmq"

new Worker(
  "super-task",
  async (job) => {
    console.log(job.processedBy) // <- job.processedBy is undefined after second run
    await new Promise((resolve) => setTimeout(resolve, 5000))
  },
  {
    connection: { url: "localhost" },
    name: "processedBy-custom-name",
  },
)

Relevant log output

processedBy-custom-name
undefined
