Scheduling Cron Not working in D9

I just ran into exactly this issue. I used the patch from the linked issue and it solves the problem.

I had been using the lightning workflow module, but it's lightning scheduler submodule had other issues already resolved in this module plus the workflow module itself is pretty much superfluous now anyway.

So I uninstalled and removed that one and installed this one instead in a couple of Drupal 10.3 sites that have been using the other module for ages. I started getting loads of these errors when running cron.

Automatically closed - issue fixed for 2 weeks with no activity.
