The fail method marks a job as failed and updates its attributes accordingly. It records the reason for failure, increments the failure count, and, if the job configuration permits, schedules the job for a retry based on the specified backoff strategy.
This does NOT save the job in the database. you must explicitly declare if you want to save it
Example Usage
const job = pulse.create('test', {});
job.fail(new Error('Unable to connect to database'));
job.save(); // If you want to save it
Parameters
reason (string | Error): The reason for the job's failure, which can be provided as either a string or an Error object. If an Error object is provided, its message is used as the failure reason.
Returns
Job: Returns the job instance, allowing for method chaining.
