`PingOhDearJob` throws error

[marcreichel]

I was trying to implement the Schedule Monitor but the queued job throws an error (see below):

Error: The script tried to call a method on an incomplete object. Please ensure that the class definition "Spatie\ScheduleMonitor\Jobs\PingOhDearJob" of the object you are trying to operate on was loaded before unserialize() gets called or provide an autoloader to load the class definition in /var/www/releases/20210413234720/vendor/laravel/framework/src/Illuminate/Queue/CallQueuedHandler.php:115

Here's the complete stack trace:

Any suggestions on what I am doing wrong?

Found the issue myself ... php artisan horizon:terminate did not run after deployment.
