Description

After loaded the "Failed Jobs" page in the browser, I'm getting deprecated warnings.

Request:
GET localhost/horizon/api/jobs/failed

Message:

json_decode(): Passing null to parameter #1 ($json) of type string is deprecated in /app/vendor/laravel/horizon/src/Http/Controllers/FailedJobsController.php on line 120

Steps To Reproduce

1. Runs Horizon
2. Dispatch a Job that will be failed
3. Open Horizon Dashboard
4. Goes to "Failed Jobs" section
5. The warning log will be displayed for each ajax request made by the "Failed Jobs" page.
