reset(): Argument #1 ($array) must be of type array, null given

Hello @UriDrupal, Could you please provide more information about the error, including the specific file and function where it is occurring? Additionally, please provide steps to reproduce the error, and specify which actions lead to this error.
Thank you.

I was using a hook_cron with a service inside. When I ran the hook_cron through simple_cron I got this error.
The error was in src/CronJobManager.php

  /**
   * {@inheritdoc}
   */
  public function getEnabledJob(string $job_id): ?CronJobInterface {
    $jobs = $this->cronJobStorage->loadByProperties([
      'id' => $job_id,
      'status' => TRUE,
    ]);

    return $jobs ? reset($jobs) : NULL;
  }

I couldn't figure out what was I doing wrong. Tried both the hook_cron way and the Plugin way, nothing worked. I am pretty sure it must have been something with my code, because the other jobs were working fine, but my hook_cron was just this:

function hook_cron() {
  \Drupal::service('my_service')->myMethod();
}

@UriDrupal, I have fixed the issue and created MR. please review it once.

Certainly doesn't hurt to be more protective in the code like this.

Thanks!
