Laravel - Queues - Ignoring Missing Models

When injecting an Eloquent model into a job, the model is automatically serialized before being placed on the queue and re-retrieved from the database when the job is processed. However, if the model has been deleted while the job was waiting to be processed by a worker, your job may fail with a ModelNotFoundException.

For convenience, you may choose to automatically delete jobs with missing models by setting your job's deleteWhenMissingModels property to true. When this property is set to true, Laravel will quietly discard the job without raising an exception:

     * Delete the job if its models no longer exist.
     * @var bool
    public $deleteWhenMissingModels = true;
