【问题描述】：
我在后端使用环回。我收到此错误

我已经搜索过stackoverflow，但没有找到答案。基本上，我试图使用 body-parser 。我经历了一个stackoverflow线程并实现了它的解决方案。我能够成功使用 body-parser。所以，这个错误已经解决了。但是，现在这个错误让我很难过。
server.js 文件
'use strict';
var loopback = require('loopback');
var boot = require('loopback-boot');
var bodyParser = require('body-parser');
var multer = require('multer');
var app = module.exports = loopback();
//code for body parsing
app.use(bodyParser.json()); // for parsing application/json
app.use(bodyParser.urlencoded({ extended: true })); // for parsing application/x-www-form-urlencoded
//app.use(multer()); // for parsing multipart/form-data
//code for body parsing ends
app.start = function() {
// start the web server
return app.listen(function() {
app.emit('started');
var baseUrl = app.get('url').replace(/\/$/, '');
console.log('Web server listening at: %s', baseUrl);
if (app.get('loopback-component-explorer')) {
var explorerPath = app.get('loopback-component-explorer').mountPath;
console.log('Browse your REST API at %s%s', baseUrl, explorerPath);
}
});
};
// Bootstrap the application, configure models, datasources and middleware.
// Sub-apps like REST API are mounted via boot scripts.
boot(app, __dirname, function(err) {
if (err) throw err;
// start the server if `$ node server.js`
if (require.main === module)
app.start();
});
在 middleware.json 中，我也更新了 parse 属性
"parse": {"body-parser#json": {},
"body-parser#urlencoded": {"params": { "extended": true }}},
由于某种原因，该错误已消失。不确定，可能还会再来。但是现在，这是错误，我看到了

很难知道你的问题是什么。最后的堆栈跟踪在
meetups.js的第 117 行显示了一个问题，您没有包含该问题。大概它正在尝试调用一个名为cb的函数，但正如错误所说，cb不是一个函数。 -
当我的输入类型不是预期的类型时遇到“值不是对象”。 type: 'object' 是预期的，但传递了一个数组
