Laravel - Queues - Chain Failures

When chaining jobs, you may use the catch method to specify a closure that should be invoked if a job within the chain fails. The given callback will receive the Throwable instance that caused the job failure:

    use Illuminate\Support\Facades\Bus;
    use Throwable;
        new ProcessPodcast,
        new OptimizePodcast,
        new ReleasePodcast,
    ])->catch(function (Throwable $e) {
        // A job within the chain has failed...
