There is a way to return a custom error message in json

public function execute() {
    $resultJson = $this->resultJsonFactory->create();
    $message = $this->getRequest()->getParam('message');
    if (strlen($message) < 3) { 
        $resultJson->setData('Message too short'); // error
    } else {
        $resultJson->setData('true'); // success
    }
    return $resultJson;
}
