It must be that the case is first saved without an assignee, or if assignee is assigned in a hook_civicrm_pre() implementation it is happening after CiviCRM's hook implementation is running.

CiviCRM validates based on what the api action.validate gives it.

It maybe possible to goto: /admin/structure/civicrm-entity/settings
"Advanced Settings"
Check "Disable pre/post hooks"

See if it works without error.

Let me know if that allows it to work.

Thank you @markusa. Yes that does allow it to work - though clearly it's a diagnostic step not a workaround. Does that give any more clues? Happy to do some more poking but I am not really clear on what structures in Drupal this hook is seeking to update.

One additional thing I have noticed is that the error does not stop the case being created, albeit with only the activities up to the one with the pre-assigned user being created.

I'm seeing this continuing to persist exactly as described. Are there any updates or paths forward?
