What happened

This action isn’t allowed in the current state. The record needs to be in a specific status before this step can happen.

Technical background

UnprocessableError from guardTransition: a state-machine transition was rejected because the current state isn’t in the allowed source states.

details.from, details.to and details.validTargets carry the diagnostics. Define allowed transitions in r.entity({ stateMachine: ... }), or check the current state before calling.
