PHP Fatal error Uncaught InvalidArgumentException: Unidentified action

It seems that on some installs of our plugin, the fatal error PHP Fatal error Uncaught InvalidArgumentException: Unidentified action is triggered.

There is a similar report that wasn't resolved: https://github.com/woocommerce/action-scheduler/issues/882

Any idea what's causing this?

At least, could you add a safeguard not to let it run into a fatal error?

Well, really any of the same possibilities outlined in #882.

Could you add a safeguard not to let it run into a fatal error?

Yes, I think we could do something similar to this fix (where bulk deletes could also result in a fatal, under certain circumstances).
