TYPO3.Neos

When a node is set with accessRoles and if somehow user reach this node and not matching the role then user see a error like "An error occurred while trying to call TYPO3\Neos\Controller\Frontend\NodeController->showAction(). Error for node: Could not convert array to Node object because the node "/sites/xxx/xxx/xxx" does not exist." on a white page.

Currently I am handling this with an Aspect to catch this validation error and redirect user to page which shows access denied message OR just add a flash message. But a better way could be there with the core itself.

/**
     * Intercepts NodeController->errorAction()
     *
     * When a Node is not accessible node is not found error is displayed.
     * This function will see if certain error number is found and then redirect
     * user to login form and block call of errorAction(). For other errors errorAction()
     * is called normally.
     *
     * @Flow\Around("method(TYPO3\Neos\Controller\Frontend\NodeController->errorAction())")
     * @param \TYPO3\Flow\Aop\JoinPointInterface $joinPoint The current join point
     * @return void
     */
