使用node js在neo4j中创建节点时出错

Question

我的代码！！

var neo4j = require('neo4j-driver').v1;
var express = require('express');
var logger = require('morgan');
var path = require('path');
var bodyParser =require('body-parser');
var app=express();
app.set('views',path.join(__dirname, 'views'));
app.set('view engine','ejs');
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
app.use(express.static(path.join(__dirname,'public')));
var driver = neo4j.driver("bolt://localhost:7687", neo4j.auth.basic("Novasys", "123456"));
var session = driver.session();
app.get('/', function(req,res){
  session
  .run('MATCH (n:Movie) RETURN n LIMIT 30')
  .then(function(result){
    var moviearr = [];
    result.records.forEach(function(record){
      moviearr.push({enter code here
        id: record._fields[0].identity.low,
        title: record._fields[0].properties.title,
        released: record._fields[0].properties.released
      });
    });

    session
    .run('MATCH (n:Person) RETURN n LIMIT 25')
    .then(function(result2){
      var personArr = [];
      result2.records.forEach(function(record){
      personArr.push({
        id: record._fields[0].identity.low,
        name: record._fields[0].properties.name
      });
      });
      res.render('index', {
      movies: moviearr,
      persons: personArr
    });
    })
    .catch(function(err){
      console.log(err);
    });
  })
  .catch(function(err){
    console.log(err);
  });
});

app.post('/movie/add',function(req,res,next){
      var title = req.body.title;
      var released = req.body.released;

      session
      .run('CREATE(n:Movie {title:{titleParam}, released:{releasedParam}}) RETURN n.title',{titleParam:title, releasedParam:released})
      .then(function(result){
          res.redirect();
        session.close();
      })
      .catch(function(err){
     console.log(err);
   });

      res.redirect('/');

});
app.listen(4000);
console.log('Server started on port 4000');

module.exports=app;   **strong text**

获取错误！！

有人能帮我解决这个问题吗？我是新的节点js以及neo4j。

提前谢谢

☼ 你好

在Neo4j数据库中是否有“个人”标签？

 session
    .run('MATCH (n:Person) RETURN n LIMIT 25')

您是否尝试过：

session
        .run('MATCH (n:Actor) RETURN n LIMIT 25')

我想你举了这个例子，但是他们用“电影”和“演员”的标签
