backoffStrategies not working

[koiszzz]

I have met a problem when using bullmq v1.39.0 . When set backStrategies in worker , the job added in queue got stuck in state delayed and never came into actived again.

const worker3 = new Worker('test3', async job => {
    console.log(`${job.name} # ${job.id} running`);
    console.log(`attemptMade: ${job.attemptsMade}`)
    throw new Error('some thing wrong');
}, {
    settings: {
        backoffStrategies: {
            jitter(attempts) {
                console.log('attempt:' + attempts);
                return 3000
            }
        }
    }
});

worker3.on('failed', (job, error) => {
    console.log(`${job.name} # ${job.id} failed`);
});
worker3.on('drained', async () => {
    console.log('worker 3 drained');
    const delayed = await queue3.getJobs(['delayed']);
    console.log('delayed jobs: ' + delayed.map(j => j.id).join(','));
});
const queue3 = new Queue('test3', {

});

(async () => {
    await queue3.add('local-test-de', {
        data: 1,
    }, {
        attempts: 3,
        backoff: {type: 'jitter'}
    });
    await queue3.add('local-test-ex', {
        data: 1
    }, {
        attempts: 3,
        backoff: {
            type: 'exponential',
            delay: 2
        }
    });
})();

It seems that when the delay of backoff setting setted bigger than 0. The job will stuck

Do you have a QueueScheduler also running? It is needed for delayed jobs. https://docs.bullmq.io/guide/queuescheduler

Thanks. The docs of retring failing job just mention QueueScheduler one time. I didn't notice that. Maybe It could add some example schedule code on retring job page . @manast
