💡 Hint

Common Mistakes

Using 'retry' method which does not exist on dispatch.

Confusing 'onQueue' with retry behavior.

The delay() method schedules the job to run after a delay, which helps in retrying failed jobs later.

Complete the code to listen for failed jobs and log the failure.

Queue::failing(function (JobFailed $event) {
    Log::error('Job failed: ' . $event->job->[1]());
});

💡 Hint

Common Mistakes

Using 'getJobId' which returns an ID, not the job name.

Using 'getQueue' which returns the queue name, not the job.

The getName() method returns the name of the failed job, useful for logging.

💡 Hint

Common Mistakes

Passing a string like '10 seconds' causes errors.

Passing a DateTime object instead of seconds.

The release() method expects an integer number of seconds to delay the retry.

Fill both blanks to define a job class that handles failure by logging and releasing after delay.

Laravel

class ProcessPayment implements ShouldQueue
{
    public function failed(Exception $exception)
    {
        Log::error($exception->getMessage());
        $this->[1]([2]);
    }
}

Using 'delete' instead of 'release' will remove the job.

Using too small or string delay values.

The release(10) method retries the job after 10 seconds delay.

5fill in blank

Fill all three blanks to create a failed job listener that logs and notifies admin.

Laravel

Queue::failing(function (JobFailed $event) {
    Log::error('Failed job: ' . $event->job->[1]());
    Notification::route('mail', '[e-mail]')->[2](
        new JobFailedNotification($event->job, $event->exception)
    );
    $event->job->[3]();
});

Using 'release' instead of 'delete' will retry the job.

Using wrong method names for notification.

This code logs the failed job name, sends a notification, and deletes the failed job from the queue.
