        return $this->getAction($this->parsedData['action']);

The expression return $this->getAction($this->parsedData['action']) could return the type null which is incompatible with the type-hinted return Conveyor\Actions\Interfaces\ActionInterface. Consider adding an additional type-check to rule them out.
