发送消息时出现内部服务器错误（500）

Question

我是ReactJS和Flux的新手，我正在某个项目上使我的办公室网站上的发送消息功能正常，在我添加一些验证之前，所有代码均正常工作。添加一些验证后，它将发送一个内部服务器错误，当某些字段为空时，该消息将不会发送到我的电子邮件中，但是当所有字段都不为空时，该消息将发送到我的电子邮件中。

这是我的views.jsx

...
export default class Message extends React.Component {
  constructor(props){
    super(props);
      this.state = {

        site: '',
        email: '',
        phone: '',
        home: '',
        subject: '',
        description: '',
        type: '',
        submitting: false
    };

    this.clearForm = this.clearForm.bind(this);
    this.handleProfileChange = this.handleProfileChange.bind(this);
    this.handleSubjectChange = this.handleSubjectChange.bind(this);

    this.handleSubmit = this.handleSubmit.bind(this);
    this.handleSubmitComplete = this.handleSubmitComplete.bind(this);
    this.handleSubmitError = this.handleSubmitError.bind(this);
  }

  componentDidMount(){
    ProfileStore.addProfileChangeListener(this.handleProfileChange);
      if(!this.state.profile){
        ProfileActions.reload()
      }
    MessageStore.addSubmitMessageChangeListener(this.handleSubmitComplete);
    MessageStore.addSubmitMessageFailChangeListener(this.handleSubmitError);//unresolved
  }    

  componentWillUnmount(){
    ProfileStore.removeProfileChangeListener(this.handleProfileChange);
    MessageStore.removeSubmitMessageChangeListener(this.handleSubmitComplete);
    MessageStore.removeSubmitMessageFailChangeListener(this.handleSubmitError);
  }

这是我针对助焊剂结构的action.js

...
function _sendMessage(messageInfo, callback) {
  jQuery.ajax({
    method: 'POST',
    url: '/api/v1/supportTickets',
    contentType: 'application/json',
    data: JSON.stringify({
      messageInfo: messageInfo
    })
  })
  .done(function(messageInfo) {
    callback(null, messageInfo);
  })
  .fail(function(err){
    console.error('Failed to send message' + JSON.stringify(err));
    callback(err);
  });
}

var MessageActions = {
  sendMessage: function(messageInfo, callback) {
    _sendMessage(messageInfo, function(err, messageInfo) {
      if(err) { return callback(err); }
      Dispatcher.dispatch({
        actionType: MessageConstants.PERFORM_SEND_MESSAGE,
        messageInfo
      });
      callback(null, messageInfo)
    });
  }
};

module.exports = MessageActions;

这是我的store.js

...
const SUBMIT_MESSAGE = 'SUBMIT_MESSAGE';
const SUBMIT_MESSAGE_FAILED = 'SUBMIT_MESSAGE_FAILED';

var MessageStore = assign({}, EventEmitter.prototype, {
   
  emitSubmitMessageChange: function(){
    this.emit(SUBMIT_MESSAGE);
  },

  addSubmitMessageChangeListener: function(callback){
    this.on(SUBMIT_MESSAGE,callback);
  },

  removeSubmitMessageChangeListener: function(callback){
    this.removeListener(SUBMIT_MESSAGE,callback);
  },

  emitSubmitMessageFailChange: function(){
    this.emit(SUBMIT_MESSAGE_FAILED);
  },

  addSubmitMessageFailChangeListener: function(callback){
    this.on(SUBMIT_MESSAGE_FAILED, callback);
  },

  removeSubmitMessageFailChangeListener: function(callback){
        this.removeListener(SUBMIT_MESSAGE_FAILED, callback);
  }
});

Dispatcher.register(function(action) {
  switch(action.actionType){
    case MessageConstants.PERFORM_SEND_MESSAGE:
      MessageStore.emitSubmitMessageChange();
      break;

    case MessageConstants.PERFORM_SEND_MESSAGE_FAIL:
      MessageStore.emitSubmitMessageFailChange();
      break;
    default:
      //noop
    }

})
export default MessageStore;

这是我通过gmail发送消息的后端

const _ = require('lodash');
const express = require('express');
const router = express.Router();

const mail = require('nodemailer');
const routing = requirerp('/lib/routing');
const api = routing.api;
const config = require('config');
const service = config.get('hits.supportTickets.service');
const host = config.get('hits.supportTickets.host');
const user = config.get('hits.supportTickets.auth.user');
const pass = config.get('hits.supportTickets.auth.pass');

const Err = requirerp('/utils/restErrors');
const validator = requirerp('/utils/restValidation');

const transporter = mail.createTransport({ //almost resolved => should move the code to another file, or just like this?
  service: 'Gmail,
  host: 'smtp.gmail.com,
  auth: {
    user: 'no.replyxxxxx@xxxx.com',
    pass: 'xxxxx'
  }
});

router.post('/', routing.requireAuth, (req, res, next) => {
  var fullName = req.body.fullName;
  var site = req.body.site;
  var email = req.body.email;
  var phone = req.body.phone;
  var home = req.body.home;
  var subject = req.body.subject;
  var message = req.body.description;
  var type = req.body.type;
  var content = 'Nama : ' + fullName + '\nLokasi : ' + site + '\nContact : ' + phone + '/' + home + '\nPesan : ' + message;

  validator.validateBody(req, { //using validator get error code 500 -> Internal Server Error
    'fullName': {
      notEmpty: true
    },
    'site': {
      notEmpty: true
    },
    'email': {
      motEmpty: true
    },
    'phone': {
      notEmpty: true
    },
    'home': {
      notEmpty: true
    },
    'subject': {
      notEmpty: true,
      in: {
        option: ['PRAYER', 'ADDRESS', 'VISIT']
      }
    },
    'descrption': {
      notEmpty: true
    },
    'type': {
      notEmpty: true
    }
  }, function(err) {
    if(Err.invalidInput(next,err)) { return; }

    const mailOptions = {
      from: fullName + '<' + email + '>',
      to: 'xxxx@xxxx.org',
      replyTo: email,
      subject: type + ':' + subject,
      text: content
    };
        
    transporter.sendMail(mailOptions, (err) => {
      if(Err.unexpected(next, err)) {
        return;
      }
      res.status(201)
      .header('Location', api('supportTickets/'))
      .json(req.body.messageInfo)
      .end();
    });
  })
});
    
module.exports = router;

有人可以给我一个建议，指出我的代码出了什么问题吗？非常感谢
