[Bug]: upsertJobScheduler not upserting jobs at times

[austinwoon]

Version

5.34.10

Platform

NodeJS

What happened?

upsertJobScheduler does not upsert jobs at times. At each redeploy, sometimes the job scheduler does not insert new jobs and no jobs get scheduled as a result. This happens undetermisitically for us

How to reproduce.

All we're doing is calling this at our index.ts fastify app file

    await this.queue.upsertJobScheduler(
      pollingWorkerName,
      {
        every: this.options.pollingFrequencyInMs ?? 2000,
      },
      {
        opts: {
          removeOnComplete: {
            count: 10000,
          },
        },
      }
    )

There are several fixes in newer versions related to the job scheduler, I think that if you upgrade to the latest version you will not be able to reproduce this issue anymore, let me know how it goes.

We just bumped the version to latest and still encountered same issue

Could it be because we have 4 instances trying to upsertJobScheduler at once?
